If you have a friend that is truely your friend, then you can discuss your problems with this person if they are being bothered by something. To not do so and the result is in a lack of communication, possibly because he has a life and doesn't spend all his days in front of a computer screen, and is removed because of it, then your definition of "Friend" is flawed, meanwhile this person that was removed is in a daze of confusion because he didn't know what he did, and tries to reach this person, his friend, in attempts to mend what was done. But in the end, one was too childish.

Guess we all can't be grown-ups, huh.
