"Psychiatrists have said every human being needs one essential friend; one they can be intimate with and expose their whole heart to and know in so doing that what they reveal about themselves will not turn up in the National Inquirer. They need a friend they can be absolutely honest with. I agree with that. But, human beings can only go with you so far. And anyway, they are not always there. Usually when I need a friend they are somewhere else: in some other state or some other town or it is the middle of the night."
