Which of your hands do you use most ? Very few of us use both of our hands well. Most of us are right-handed. Only about five people out of a hundred are left-handed. New-born babies can take things with either of their hands, but in about two years they like to use their right hands. Scientists don’t know why this happens. They have studied it. They think our animal ancestors(祖先) are right-handed. This may not be true. Monkeys are our closest relations in the animal world. Scientists have found that monkeys like to use one of their hands more than the other—but it can be either hand. There are as many right-handed ones. Next time you visit the zoo, watch the monkeys carefully. You’ll see that some of them will swing(摆动)from their right hands and others will use their left hands. But most human beings(人类) use their right hands better and this makes life difficult for the left-handed ones. We live in a right-handed world.

Just like any relationship, best friendships depend on trust, promise, respect and interests. When any of these elements(要素) is missing, the friendship will be hard to go on. If the trust is totally broken, you may not be able to forgive him/her. Sometimes a friendship ends because either you or your friend gets tired of putting the heart into it. This can happen when one of you finds a new friend or even a new hobby that takes up much time. Or, perhaps you find the relationship is always going in an unhealthy way and you want some distance. Other times, you simply change and want to leave each other. Sure, it seems sad at the time, but it’s completely normal. Not all friendships are meant to last forever. So, what should you do if something like this happens to you? Read on for some friendly advice.
Whatever the reason you’re breaking up with your best friend, always remember that he/she was once super important to you. Take the time to sit down privately and tell him/her what’s going on and why. Don’t send him/her an unpleasant e-mail or just start ignoring(不理睬) him/her. In fact, maybe he/she has known there’s a problem and would be willing to have a heart-to-heart chat. If you’re not sure about wanting an end forever, you could suggest you two take a break from each other. If, after a while, you realize why you became the best friends in the beginning, you can try getting back to your former behaviors. Whatever you do, be honest about your feelings while having respect for his/hers. And if you both agree the BFF thing is over, make sure not to be enemies.
