Hello, let me ask a hypothetical question. Answers, foolish answers, or any kind of answers are welcome.
(that "you" in the situation is not me)
Situation:
Once in your life, there is a good friend of you, he was very kind to you and often help you out with stuffs, share his food, whatever.
However, later on, he become someone who is annoying somehow. And you decided not to have such a friend any more.
Unfortunately, he keep trying to find you via whatever method, such as MSN messenger. How would you deal with such a guy? Yell at him? Punch him in the face? Or just quietly change your contact information/block-list?
Discuss.
