Dear Graham,

    My partner and I have recently lost a pet quite suddenly. Normal life is continuing with so much sadness for my pet meant so much to me. Lots of people won't understand my feeling this way about the death of an animal. This obviously isn't the first time someone in my life has passed away: when I was younger we lost elderly relatives who I loved very much, and naturally much-loved family pets died occasionally too. But this has hit me so much harder. I put so much love into the relationship and I'm just finding it hard to get my head around the fact that it's gone.

    Thank you for taking the time to read this.

Dear Anon,

    Something you loved deeply has gone from your life, so of course you are sad. We love our pets differently from family members or friends and part of that is because we know they will probably die before us. Our time with our dogs or cats is precious precisely because we understand it is limited.

    As humans, we go through most of life understanding we would die one day. But animals don't. We are the keeper of the secret. Of course, living a life unencumbered(不受妨碍) by thoughts of death means that our pets, in general, lead very simple, happy lives. It's one of the reasons why they are such a joy to be round. You are, of course, correct when you say that many people don't understand your grief, so don't talk to them. Share your feelings with like-minded souls. I'm sure a simple search online will reveal many practical advice for moving on.

    And when you are ready, you can welcome another animal into your life and then you will enjoy happiness again.

    Knowing what to do at checkout and properly preparing for it can turn a potentially heated situation into a quick thank you add goodbye. Below we made a list of five things you should remember at hotel checkout.

Don't be late to check

    Hotels may add an extremely high price for being just a half hour late. If you know you won't make the cutoff time, it never hurts to call ahead and try to negotiate away a potential charge.

    Don't forget to double cheek the room and safe

    Make sure you don't leave things behind. If you have an early flight or checkout time, pack up as much as you can the night before so that last-minute rush isn't too annoying. Also, be sure to take out anything in the room safe.

    Don't forget to tip the housekeepers

    It's always polite to leave some money for the people keeping your room clean.

    Don't ignore the detailed bill

    You may be in a rush, but give the detailed hill a careful look to see if the hotel charge is different from the rate you initially booked.

    Don't get angry

    Shooting at the assistant manager standing behind the front desk probably won't help.

    When dealing with an unexpected item on the bill. Think about how difficult it can be to deal with annoyed customers. Keep calm and things may be solved better and sooner.

    Memory, they say, is a matter of practice and exercise. If you have the wish and really make a conscious(自觉的) effort, then you can quite easily improve your ability to remember things. But even if you are successful, there are times when your memory seems to play tricks on you.

    Sometimes you remember things that really did not happen. One morning last week, for example, I got up and found that I had left the front door unlocked all night, yet I clearly remember locking it carefully the night before.

    Memory "tricks" work the other way as well. Once in a while you remember not doing something, and then find out that you did. One day last month, for example, I was sitting in a barber shop waiting for my turn to get a haircut, and suddenly I realized that I had got a haircut two days before at the barber shop across the street from my office.

    We always seem to find something funny and amusing in incidents caused by people's forgetfulness or absent-mindedness. Stories about absent-minded professors have been told for years, and we never get tired of hearing new ones. Unfortunately, however, absent-mindedness is not always funny. There are times when "tricks" of our memory can cause us great trouble.

    Maybe it's because it was our first purchase as homeowners. The salesman must have spotted just how green we were, so he began persuading. And soon he led us to a classic leather chair. All these years later, I remember he used words like rich and handsome, the thing every living room needed.

    We believed him. So we bought that chair — just less than $100, a great deal in the 1970s for a young couple!

    How we loved that chair! It always occupied a place of honor in our various living rooms, moving with us from our first tiny house to our beloved new house.

    Somehow, conversations were better on that chair, and life was more fun around it. Three daughters spilled their secrets on it. Old friends seemed to be attracted by it on those wonderful occasions. Crazy as it sounds, that leather chair seemed to have — well, powers. All for good.

    At first, we didn't really care that the leather was showing signs of wear or that it had lost its sheen (光泽). But in our most recent move, when the chair was moved in our new living room, it suddenly looked terribly lonely sitting close to newly painted walls and a couple of shiny new tables.

    My husband and I tried but still we couldn't ignore the rough spots. Our chair had a skin disease. Even our adult kids raised eyebrows, urging us to at least remove the chair to some dark comer of the room. Neither of us could imagine such a retirement for it.

    So we had an inspired idea. We'd call in an upholsterer (修理工) to give our old chair a whole new life. Our friend Joe studied the chair and then took out a simple leather conditioner. He explained that although it wouldn't work miracles, it would definitely get our weary chair looking younger again. It certainly doesn't look new, but its seat and back are shining, and some of its deeper wrinkles have lightened.

    Best of all, it's back in the living room, looking like a wise old friend to the furniture around it. And, yes, there it will stay.

    Because some things, like some people, just deserve a happy old age.

Scientists have long thought about whether each animal species has a different language, much like different human languages that we cannot understand. Language experts agree on the fact that the way animals communicate through various calls does not fit the definition of human languages.

Animal calls are not considered a language because the calls are limited to signals related to food activities, warning about the presence of enemies and so on. They lack the characteristic of productivity that all human languages share. That is — humans create new expressions every day by combining different words to express meanings. Animal calls are fixed in their meanings, while human language goes further and includes expressions of complex ideas that do not have a limit.

However, animals do communicate. People who study humans believe that people speak with their entire bodies. To express a message, one does not always need words. Have you ever shared a private joke with your friends across the table? All you did was to give them a self-satisfied smile, Animals can communicate in much the same way as humans do. Although animals do not have the ability to speak words, they can use other methods, such as gestures, movements, calls and their sense of smell. In short, most of their communication is not related with speech.

If animals can make noises, why can't they talk? Humans and animals both have the necessary organs that produce sounds, such as lungs, throat, voice box, lips and tongue. But the differences lie in the movement and relative position of these organs that make it possible for us to speak.

When humans developed from apes, a lot of our features were improved to better shape sounds along the way. The mouth started getting smaller and the neck grew longer. All other animals, including our closest animal relatives — chimpanzees, have little similarity, which determines humans' ability to speak.

With such a strong artistic heritage, it's no surprise that England knocks it out of the park when it comes to world-class art galleries. These are the galleries you need to add to your must-visit list.

Royal Academy of Arts (RA), London

Not your standard gallery, the Royal Academy of Arts is led by artists to promote not just the appreciation of art, but its practice. It is world-famous for hosting some exhibitions that get everyone talking. Besides, what sets the RA apart is its engagement with the public through participatory experiences, allowing visitors to not only view art but become part of it in innovative ways.

Sainsbury Centre for Visual Arts, Norwich

Sitting on the edge of the University of East Anglia's campus, the Sainsbury Centre holds a collection of remarkable works of art spanning over 2,000 years. Inside the seminal Norman Foster building, you'll find artworks from around the world, including some stunning pieces of European modern art by Degas, Francis Bacon, and Alberto Giacometti.

Yorkshire Sculpture Park, West Yorkshire

Tearing up the rulebook when it comes to how we traditionally view art, the Yorkshire Sculpture Park strives to break down barriers by showing works from British and international artists in the open air. Set in hundreds of acres of West Yorkshire parkland, you'll see sculptures by some of the leading artists of the 20th century.

Whitworth, Manchester

After a sky-high £15 million development, the Whitworth is becoming one of the premier galleries in the north of England. Making full use of its picturesque park setting, the gallery has a beautiful art garden and a sculpture terrace (露台), all waiting to be explored. Inside the gallery, you can view an exciting programme of ever-changing exhibitions.
