Now and again,people choose to leave our friend list,sometimes we delete them,mainly because they havent been around much.Recently i noticed some body left my list,and it took me some time to find out,and eventually i did.
I always try to find who left my list and why.That can be tricky.People have every right to leave your friend list when they want and for whatever reason.
But general atiquets and common sense says that if you break contact with someone,leave a note. ;) Walking quietly out of the door makes you insignificant.
Oh well,may be i am over reacting :)
