Not all friendships are created equal. Some friends get along; others struggle to avoid conflict. Conventional wisdom holds that the tenor of a friendship with someone who is nice differs from that with someone who is mean, such that the former discourages negative interactions whereas the latter aggravates them. Although it is logical to assume that children who are mean have friendships characterized by growing strife and that children who are nice report little of the same, these assumptions have not yet been tested in the real-world friendships of children.
