I wish I knew to whom I should give credit for this saying--long a favorite of mine--but I just don't remember from whence I learned it. Nevertheless, many a truth is spoken in jest:

What's the difference between a friend and a good friend? A friend will help you move, no questions asked. A good friend will help you move a body, no questions asked.

So how many friends do you really have? And how many good friends? Or more poignantly, are you a friend to many? Are you a good friend to any?
