There is no other species that interacts so widely with other members of their species. Solid friendships provide needed validation that a person is valuable and of interest to other people. Relationships help people feel that they’re worthy, that they are capable, that they can set goals and accomplish them, and that they can control their life.(21)Friendship could be represented by three concentric circles as very close, close, and not-so-close but still meaningful personal ties. A person’s inner circle usually includes close family members and friends who are thought of as family. Close friendships display strong support and affection. A close friend fills an invaluable role as a confidant, someone who listens and pays attention to you, is willing to help you, and has shared interests. There is give-and-take and often a balance that doesn’t put too much weight on one party. Developing and maintaining friendships requires continuous attention. Give-and-take is important. Other elements of solid friendships include paying attention to what’s going on in a friend’s life, seeking out and participating in shared interests and activities, and being able to confide deeply to a friend.
