What does a friend have to do to no longer be considered a friend? How many times must one invite a friend to do something and he declines before one no longer asks? How many lies must one be told before all trust is gone? How awkward do situations have to get until one stops being around the friend? How many times does a friend have to disappoint another before he no longer is a friend?
I'm guessing that if I'm asking the questions, I already know the answers.
