When was the last time you did something really fun with one of your parents—just the two of you?

    Parents who take their young children to music，swimming and art classes often stop arranging such activities once their kids are older and in school all day.But it doesn't have to be that way.Doing something enjoyable with your kids just might make you look at each other in a whole new way，especially if you do it through a class or an event.When parent and child become students together，it puts them on the same level，at least for a while.

“I really like parents to come to class with their kids—they start sharing things and talking about what they're doing and what they like，” said art teacher Pyper Dixon.

    However，finding something new in common is a big  choice for them，especially when kids get involved in sports and other after­school activities.But it's possible to learn a new skill or hobby together.

    That's certainly true of Lauren,11，from Silver Spring，who is in Dixon's class with her father，Dennis.“I was just going to drop her off，” Dennis said，“but Dixon persuaded me to stay.”

    Now Lauren gets to nag her father about doing his art homework.“He always leaves it to the last minute，” she said.“But then he'll turn around to do amazing drawings，”  she added.“We have different styles of drawing，so it's interesting  to talk it over with him.”

    Without the Saturday morning art class，Dennis said，he  would be reading the paper，and Lauren would be on her own in her room or on the computer.But they talk more now.“I can't think of an experience where you communicate with your kid so closely，” he said.

    Suppose you're in a rush, felling tired, not paying attention to your screen, and you send an email that could get you in trouble.

    Realisation will probably set in seconds after you've clicked “send”. You freeze in horrors and burn with shame.

    What to do? Here are four common email accidents, and how to recover.

    Clicking “send” too soon

    Don't waste your time trying to find out if the receivers has read it yet. Write another email as swiftly as you can and send it with a brief explaining that this is the correct version and the previous version should be ignored.

    Writing the wrong name

    The sooner you notice, the better. Respond quickly and briefly, apologizing for your mistake. Keep the tone measured: don't handle it too lightly, as people can be offered, especially if your error suggests a misunderstanding of their culture(i.e. incorrect ordering of Chinese names).

    Clicking “reply all” unintentionally

    You accidentally reveal(透露)to entire company what menu choices you would prefer at the staff Christmas dinner, or what holiday you'd like to take. In this instance, the best solution is to send a quick, light-hearted apology to explain your awkwardness. But it can quickly rise to something worse, when everyone starts hitting “reply all” to join in a long and unpleasant conversation. In this instance, step away from your keyboard to allow everyone to calm down.

    Sending an offensive message to its subject

    The most awkward email mistake is usually committed in anger. You write an unkind message about someone, intending to send it to a friend, but accidentally send it to the person you're discussing. In that case, ask to speak in person as soon as possible and say sorry. Explain your frustrations calmly and sensibly—see it as an opportunity to clear up any difficulties you may have with this person.

    Last summer I sat at a long picnic table near a breathtaking mountain. While the parents were eating dinner, the kids ran up a trail in search of a secret fort. Twenty minutes later one excited little boy, James, interrupted the adult conversation.

    “Mom, Mom, you can't believe what we found!”

    Lovingly, his mother smiled and whispered, “I can't wait to hear, James, but grown-ups are talking, and there will be a pause in the conversation. Please wait for the pause.”

    On my other side, another boy came running up to his mother with equal enthusiasm.

    “Mom, Mom, we had so much fun—”

    “I am talking! Don't interrupt,” she said.

    “But, Mom—”

    “Be quiet! Can't you see that I am talking?”

    “But Mom we found the—”

    “Shut up, Steve!” she yelled.

    My heart sank. I knew what was coming. James, on my right, patiently waited for the pause, enthusiasm still alive and well. Steve, on my left, walked away from the table, looking shamed, carrying with him stories of secret forts never to be shared.

    What markedly different messages to the child! “Wait for the pause” versus “Shut up” gets incorporated (包含)so differently into a child's developing sense of self.

    Harsh(刺耳的) words have bad effects. That's why I want you to promise to delete the phrases “Shame on you” or “You should be ashamed” from your vocabulary. I have seen countless patients whose parents' thoughtless words echoed in their heads and chipped(消除) away at their self-worth, even decades later.

    So we have to discipline ourselves to make our instructions constructive. One great tool is to look for positive behavior to reinforce. Don't ignore the things that your kids are doing right. Thank your children. Tell them that you noticed how they waited patiently or cleared their plate without being asked. Chances are that they will do it again. Let them feel noticed, appreciated, and valued. There's no better way to shape behavior.

    He met her at a party. She was outstanding; many guys were after her, but nobody paid any attention to him. After the party, he invited her for coffee. She was surprised! In order not to appear rude, she went along.

    As they sat in a nice coffee shop, he was too nervous to say anything and she felt uncomfortable. Suddenly, he asked the waiter, "Could you please give me some salt? I'd like to put it in my coffee."

    They stared at him. He turned red, but when the salt came, he put it in his coffee and drank. Curious, she asked, "Why salt with coffee?" He explained, "When I was a little boy, I lived near the sea. I liked playing on the sea. I could feel it salty, like salty coffee. Now every time I drink it, I think of my childhood and my hometown. I miss it and my parents, who are still there."

    She was deeply moved. A man who can admit that he's homesick must love his home and care about his family. He must be responsible. She talked too, about her far away hometown, her childhood, her family. That was the start to their love story.

They continued to date. She found that he met all her requirements. He was kind, warm and careful. She thought she would have missed the catch if not for the salty coffee! So they married and lived happily together. And every time she made coffee for him, she put in some salt, the way he liked it.

    After 40 years, he passed away and left her a letter which said:

    My dearest, please forgive me my life-long lie. Remember the first time we dated? I was so nervous that I asked for salt instead of sugar. Sweetheart, I don't exactly like salty coffee. But as it means so much to you, I've learned to enjoy it. Having you with me was my greatest happiness. If I could live a second time, I hope we can be together again, even if it means that I have to drink salty coffee for the rest of my life.

A team of scientists say that seawater flowing underneath and into gaps in the Thwaites Glacier in Antarctica is contributing to the melting of the massive ice formation.

"The worry is that we are underestimating the speed that the glacier is changing. It would be disastrous for coastal communities around the world," Christine Dow, co-author of the study, said in a press release.

At roughly 80 miles across, Thwaites is the widest glacier in the world, nicknamed the "Doomsday Glacier" for the fatal effects its melting could have on global sea-level rise. Each year, it loses about 50 billion tons of ice, which comprises roughly 4% of all sea-level rise worldwide, according to the International Thwaites Glacier Collaboration. One estimate predicted that the total loss of Thwaites could cause average global sea levels to surge by more than two feet.

In the study, the team of glaciologists used radar data by Finland's ICEYE commercial satellite program to get a better idea of what's happening below the surface of the glacier. They found that seawater flows in and away from, the glacier with the tides, mixing with freshwater, but some of that warm ocean water also travels deep beneath the ice formation, going "through natural passages" or collecting "in holes" and becoming trapped.

"There are places where the water is almost at the pressure of the overlying ice, so just a little more pressure is needed to push up the ice," said Eric Rignot, the study's lead author. "The water is then squeezed enough to jack up a column of more than half a mile of ice."

Dow suggested that additional ice sheet modeling could help scientists better understand what's happening under these major glaciers and develop a more precise timeline of expected sea-level rise across the world. "This work will help people adapt to changing ocean levels, along with focusing on reducing carbon emissions to prevent the worst-case assumption," Dow said.
