 Oscar Wilde said that a true friend will stab you in the front. And I think that that's an important quality in a friend, the willingness to stab you in the front. Lines will get crossed. Feelings will be hurt. That's sort of what lines and feelings are there for. A real friend will come back across that line and soothe hurt feelings. You know, she'll forgive your crossing that line. What qualities make for great buddyhood on stage or in the theater?
