Everyone needs a friend, because we are not the only one in the world. We need someone to talk to and share our happiness and sorrow. Last night, I saw a movie, the protagonist's friend asked him what was a friend, and he gave the answer that a friend was someone you can talk about your secret and you would share food with. It is a child's opinion, and it is simple and real. A friend is someone who we can trust, we don't have to hide ourselves and just who we are. We will feel comfortable with them. When we are in trouble, we will think of them and they will come to help.
