When a child has peer approval, it gives him a sense of importance in a group.
Children learn different ways of acting and relating to others by watching and playing with peers.
Unfortunately, not all kids are successful in their attempts at making friends and interacting positively with peers. Developmentally, children and adults think about friendships differently. Even after seeing you at your worst, she still likes you. Children take another perspective. As they grow in age and understanding, they eventually develop an adult concept of a friend, but this typically does not happen until mid-adolescence.
