Friendship
Friendship is a relationship of mutual affection between people. It is a stronger form of interpersonal bond than an "acquaintance" or an "association", such as a classmate, neighbor, coworker, or colleague.

In some cultures, the concept of friendship is restricted to a small number of very deep relationships; in others, such as the U.S. and Canada, a person could have many friends, and perhaps a more intense relationship with one or two people, who may be called good friends or best friends.
Other colloquial terms include besties or Best Friends Forever (BFFs). Although there are many forms of friendship, some of which may vary from place to place, certain characteristics are present in many such bonds. Such features include choosing to be with one another, enjoying time spent together, and being able to engage in a positive and supportive role to one another.Sometimes friends are distinguished from family, as in the saying "friends and family", and sometimes from lovers (e.g., "lovers and friends"), although the line is blurred with friends with benefits. Similarly, the friend zone is a term for when someone is restricted from rising up to the status of lover, hence the name (see also Unrequited love).

Friendship has been studied in academic fields, such as communication, sociology, social psychology, anthropology, and philosophy. Various academic theories of friendship have been proposed, including social exchange theory, equity theory, relational dialectics, and attachment styles.

Developmental psychology

Childhood

The understanding of friendship in children tends to be more heavily focused on areas such as common activities, physical proximity, and shared expectations.: 498  These friendships provide opportunity for playing and practicing self-regulation.: 246  Most children tend to describe friendship in terms of things like sharing, and children are more likely to share with someone they consider to be a friend.: 246  As children mature, they become less individualized and are more aware of others. They gain the ability to empathize with their friends, and enjoy playing in groups. They also experience peer rejection as they move through the middle childhood years. Establishing good friendships at a young age helps a child to be better acclimated in society later on in their life.Based upon the reports of teachers and mothers, 75% of preschool children had at least one friend. This figure rose to 78% through the fifth grade, as measured by co-nomination as friends, and 55% had a mutual best friend.: 247  About 15% of children were found to be chronically friendless, reporting periods without mutual friends at least six months.: 250 Studies have shown that friendships in childhood can assist in the development of certain skills, such as building empathy and learning different problem solving techniques.

Coaching from parents can be useful in helping children to make friends. Eileen Kennedy-Moore describes three key ingredients of children's friendship formation: (1) openness, (2) similarity, and (3) shared fun. Parents can also help children understand social guidelines they haven't learned on their own. Drawing from research by Robert Selman and others, Kennedy-Moore outlines developmental stages in children's friendship, reflecting an increasing capacity to understand others' perspectives: "I Want It My Way", "What's In It For Me?", "By the Rules", "Caring and Sharing", and "Friends Through Thick and Thin."

Adolescence

In adolescence, friendships become "more giving, sharing, frank, supportive, and spontaneous." Adolescents tend to seek out peers who can provide such qualities in a reciprocal relationship, and to avoid peers whose problematic behavior suggest they may not be able to satisfy these needs.
