Friends.

I think that people need friends so that people aren't lonely in life. If people are lonely then they are unhappy and if they are unhappy then they are going to be depressed. If you have a friend you can do stuff that you wouldn't do by yourself. Like going bowling or play soccer.

You know if friends are friends if they are  trust worthy with you. Some times bad friends will make you do stuff you don't want to do. But a good friend will tell you not to do something bad or anything stupid.  And a friend gives you support through any problem, like broken relationships. So if someone doesn't have any friends, why don't you become that person's friend.
