　　Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk, laugh and do things with. Surely, there are times when we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend.

　　No two people are the same. Sometimes friends don't get along well, which doesn't mean that they no longer like each other. Most of the time they will go on being friends. Sometimes friends move away, then we feel very sad. We miss them much, but we can call them and write to them. Maybe we would never see them again, and we can make new friends.

Many places are named after men and women, if they are friendly to people in a town. Some libraries are named this way. So are some schools. We think of these people when we go to these places.

　　There's more good news for people, if they have friends. These people live longer than those people if they don't have friends. Why? It could be that they are happier.
