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. Sure, 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. That doesn’t mean 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 very much. But we can call them and write to them. Maybe we would never see them again. And we can make new friends. It is surprising to find out how much we like new people when we get to know them. Families sometimes name their children after a close friend. Many places are named after men and women, if they are friendly to people in a town. Some libraries are named in this way. So are some schools. We think of these people when we go to these places.

There is more good news for people, if they have friends. These people live longer than those people who don’t have friends. Why? It could be that they are happier. Being happy helps you stay well. Or it could be just knowing that someone cares. If someone cares about you, you take better care of yourself.
