Friends on Yahoo messenger

It is really difficult to keep track of all of them because we move to different places due to jobs, and other factors.And sometimes,subtle differences also cause minor conflicts which though not flared up,are enough to keep away from them.I know that it happenned in my case.some of my friends whom I knew when I was in US,did some silly things due to which we got cut off from one another.I even re-contacted some of them But they don't contact me anymore.It is disheartening but nothing can be done:)

I also had to block some friends but that was not on yahoo,it was on hotmail.That email id expired anyway recently because I didn't access my hotmail in more than a month!
