Britons may like to complain a lot, but they rarely do so right now, explains BBC writer Ruth Margolis. They would rather grumble (发牢骚) afterward. This is because Britons hate to put someone out and cause any embarrassment. Margolis writes, “For instance, I'm much more comfortable just leaving that piece of raw chicken on my plate instead of complaining to restaurant staff. But beware: if this kind of thing happens when you're dining with an American, they will most likely speak up on your behalf and not understand why you find this ashamed.”

    In a BBC blog post comparing cultural differences between the UK and the US, Margolis mentions a few other things that Americans like to do that are offensive to Britons.

● Not making introductions

    Margolis says most Britons dislike this approach because “talking to strangers without being introduced gives them a stomachache”. Americans rarely introduce a new friend to their friends at parties. Strangers are supposed to introduce themselves.

● “Quite” good

    Using “quite” to mean “very” happens a lot in the US. But if you are invited to a dinner party in Britain, don't describe the meal as “quite good” if you want to express high praise. To Britons' ears, “quite” detracts from the “good”: the meal was OK but could have been better.

● Money Talk

    Americans can talk about money subjects for hours without feeling uncomfortable. For Britons, says Margolis, “Talking about how much we make is unthinkable — even 1ess so than discussing our feelings.”

● Over-politeness

    “It's not that I want shop assistants to be actively rude. But neither do I want to expend energy responding to someone who's been paid to ask: ‘How are you today?'” says Margolis. In the US, it is not unusual to be greeted by a perfect stranger as “honey” or “sweetie”. But Margolis says Britons find put-on friendliness, especially in stores, deeply irritating.

    You use her as a shoulder to cry on. She texts you back with casual jokes. But she, Xiaoice, is only a virtual chatbot（虚拟聊天机器人）.

    Xiaoice, Microsoft's latest artificial intelligence robot, was briefly released in 2014, and returned to WeChat in 2015, where she became a big hit. Millions of young Chinese now exchange messages with her daily, The New York Times reported. On WeChat, Xiaoice is an official account. After following it, users can start text-based conversations with Xiaoice.

    “Her incredible learning ability was why people loved to talk with Xiaoice,” Liu Jinchang, a researcher at High-tech Research and Development Center under the Ministry of Science and Technology, told China Daily. Apart from her ability to identify photos and send emojis（表情符号） in conversations, Xiaoice gains 45 percent of her knowledge from interacting with users, China Daily reported.

    Chatbot programs first appeared in the mid-1960s in the US. Driven by top tech companies, they are becoming smarter and more common. For instance, IBM's latest artificial intelligence program served as an academic consultant at Australia's Deakin University, answering students' questions about course schedules and financial aid. Apple's Siri and Amazon's Alexa have been used as voice assistants who can read news, play music and even make jokes for their users.

    These programs are expected to move beyond smartphones, into televisions, cars and living rooms, The New York Times pointed out. However, it may take decades before scientists develop a “Samantha”, the advanced chatbot seen in the fiction film Her. In the film, Samantha has a romantic relationship with her user played by US actor Joaquin Phoenix. Many viewers were enthusiastic about this fantasy of virtual soul mates.

    Big Brothers Big Sisters is based on the simplicity and power of friendship．It is a program which provides friendship and fun by matching vulnerable young people (ages 7-17) with a volunteer adult who can be both a role model and a supportive friend.

    Volunteer tutors come from all walks of life—married, single, with or without children. Big Brothers and Big Sisters are not replacement parents or social workers. They are tutors: someone to trust, to have fun with, to talk and go to when needed.

    A Big Sister and Little Sister will generally spend between one and four hours together three or four times each month for at least twelve months. They enjoy simple activities such as a picnic at a park, cooking, playing sport or going to a football match. These activities improve the friendship and help the young person develop positive self-respect, confidence and life direction.

    Big Brothers Big Sisters organizations exist throughout the world. It is the largest and most well-known provider of tutor services internationally and has been operating for 25 years.

    Emily and Sarah have been matched since 2008. Emily is a 10-year-old girl who has experienced some difficulties being accepted by her schoolmates at school. “ I was pretty sure there was something wrong with me.”

    Emily's mum came across Big Brothers Big Sisters and thought it would be of benefit to Emily by “providing different feedback (反馈) about herself other than just relying on schoolmates to measure her self-worth.

    Sarah wanted to get involved in a volunteer program. “I googled it and found out how to be a part of it. I thought it would be fun for me to get involved in making time to do something because sometimes it is all work and no play.”

    Big Brothers Big Sisters has been of great benefit and enjoyment to both Emily and Sarah. They love and look forward to their time together and the partnership has certainly helped Emily be more comfortable in being the wonderful, happy and unique girl she is!

    I had been in the city for some time and was coming home. I missed my boat and decided to travel on an old ship. I knew that it would not be a comfortable journey but I had no time to wait for another boat.

    Hardly had we left the port when I saw the dog Gulliver, the captain's favourite dog, for the first time. What a big dog it was! I had never seen one that could frighten me so much!

    On the third day the ship caught fire. Nobody tried to put it out. The ship began sinking and all the men rushed to the life-boats. I saw no chance of getting away in a boat. Suddenly I remembered there was a life-raft on the ship. I had no time to lose, so I immediately rushed towards the raft and pushed it overboard.

    In jumping down onto the raft I hurt myself badly and was unconscious for some time. When I came to, I found there was no sign of a life-boat. Every man who had been on board the ship must have gone down with her. I was the only one who was saved.

    Then I saw Gulliver was coming fast towards the raft. He struggled a long time before he managed to get onto it. I wanted to push him back into the water but did not dare to move. The dog shook himself, went to the other end of the raft and lay down. I didn't dare to sleep that night. I must watch him. In the moonlight I could see his eyes were open. He was watching, too.

    The fence was long and high. He put the brush into the whitewash and moved it along the top of the fence. He repeated the operation. He felt he could not continue and sat down.

    He knew that his friends would arrive soon with all kinds of interesting plans for the day. They would walk past him and laugh. They would make jokes about his having to work on a beautiful summer Saturday. The thought burned him like fire.

    He put his hand into his pockets and took out all that he owned. Perhaps he could find some way to pay someone to do the whitewashing for him. But there was nothing of value in his pockets-nothing that could buy even half an hour of freedom. So he put the bits of toys back into his pockets and gave up the idea.

    At this dark and hopeless moment, a wonderful idea came to him. It filled his mind with a great, bright light. Calmly he picked up the brush and started again to whitewash.

    While Tom was working, Ben Rogers appeared. Ben was eating an apple as he walked along the street. As he walked along it, he was making noises like the sound of a riverboat. First he shouted loudly, like a boat captain. Then he said "Ding—Dong-Dong", "Ding—Dong— Dong" again and again, like the bell of a riverboat. And he made other strange noises. When he came close to Tom, he stopped.

    Tom went on whitewashing. He did not look at Ben. Ben stared a moment and then said: "Hello! I'm going swimming, but you can't go, can you? "

    No answer. Tom moved his brush carefully along the fence and looked at the result with the eye of an artist. Ben came nearer. Tom's mouth watered for the apple, but he kept on working.

    Ben said, "Hello, old fellow, you've got to work, hey?"

    Tom turned suddenly and said, "Why, it's you, Ben! I wasn't noticing."

    "Say—I'm going swimming. Don't you wish you could? But of course you'd rather work—wouldn't you? Of course you would."

    Tom looked at the boy a bit, and said, "What do you call work?"

    "Why, isn't that work?"

    Tom went back to his whitewashing, and answered carelessly.

    "Well, maybe it is, and maybe it isn't. All I know is, it suits Tom Sawyer."

    "Oh come, now, you don't mean to say that you like it?

    The brush continued to move.

    "Like it? Well, I don't see why I shouldn't like it. Does a boy get a chance to whitewash a fence every day?"

    Ben stopped eating his apple. Tom moved his brush back and forth, stepped back to look at the result, added a touch here and there, and stepped back again. Ben watched every move and got more and more interested. Soon he said, "Say, Tom, let me whitewash a little."

    Tom thought for a moment, and was about to agree, but he changed his mind.

    "No-no-it won't do, Ben. You see, Aunt Polly wants this fence to be perfect. It has got to be done very carefully. I don't think there is one boy in a thousand, maybe two thousand, that can do it well enough."

    "No——is that so? Oh come, now——let me just try. Only just a little."

    "Ben, I'd like to, but if it isn't done right, I'm afraid Aunt Polly …"

    "Oh, I'll be careful. Now let me try. Say—I'll give you the core of my apple."

    "Well, here—No, Ben, now don't. I'm afraid …"

    "I'll give you all of it."

    Tom gave up the brush with unwillingness on his face, but joy in his heart. And while Ben worked at the fence in the hot sun, Tom sat under a tree, eating the apple, and planning how to get more help. There were enough boys. Each one came to laugh, but remained to whitewash. By the time Ben was tired, Tom sold the next chance to Billy for a kite; and when Billy was tired, Johnny bought it for a dead rat——and so on, hour after hour. And when the middle of the afternoon came, Tom had won many treasures.

    And he had not worked. He had had a nice idle time all the time, with plenty of company, and the fence had been whitewashed three times. If he hadn't run out of whitewash, Tom would have owned everything belonging to his friends.

    He had discovered a great law of human action, namely, that in order to make a man or a boy want a thing, it is only necessary to make the thing difficult to get.

    Everyone can try his best to achieve something. We don't need to be the best, but to challenge the limits of what we are capable of. I gained this belief from my third grade teacher, the most special, honored, trustworthy, and beloved person in my life.

    Mr. Myrus was always perfectly dressed and spoke with the belief that talking to an eight－year－old child didn't mean he had to sacrifice proper statements or grammar. And he was demanding, but he wasn't unreasonable or cruel. He simply felt that no matter what your best was, you should achieve it.

    Luckily enough, I met him again as my eighth grade math teacher. I was not, nor ever will be, gifted in math. I remember my struggles in class. “I don't know the answer,” I would say. "I can't do it!" “Perhaps you don't know the answer,” he would say quietly. “Do you think we might figure it out together? How do you know what you can do if you don't have a try？”

    Mr. Myrus lived around the corner, and I would often stop by to talk while he worked in his garden. I knew there was someone who let me know that if I had really tried, that was enough. “Don't be so hard on yourself,”he'd say.“ Stop blaming yourself. Did you try your best? Well, then you're not a failure,” he often told me these words.

    Mr. Myrus died in 1978. I had never thought about his death. He was too young. I felt sorry. But when I think about him now, I don't feel so sorry. He taught me to be kind, not only to others, but to myself. He taught me my own value. He taught me about honor, about truth, and about doing my best and he also taught me that all feelings and beliefs have dignity and deserve respect. And of all the things I know, I believe that we can't all be “the best”, but we can, each of us, be our best. And I know that's true because Mr. Myrus told me that.
