Hi again Fuzzy,
I don't think people leave PC because of one person. (I cannot see for the life of me, why you would think you would make someone want to leave because of something you did or said. You're always there to give hugs and have something supportive to say. At least for me this has been the case and your posts I've read to others.)

For every one negative person I think there are 10 positive people here on PC.
So,I think sometimes it's an accumulation of things going on at PC that makes them leave-maybe it's too exhausting reading about so many other's people's pain and it leaves them feeling helpless or feeling like in comparison you have nothing to complain about (I get to feeling like that a lot.) or it may be that something is going on in their RL that's making them not as accessible to PC.
