Your sensitive and that means easily hurt. That person was out of line yes, but sweetie, it isn't worth giving up. I had someone even pm me once and called me an alpha bitch.
I don't think I am, but it doesn't matter, I'm certainly not going to let some no-mind rude person make me quit trying to help all the folks and their pupsters. Hang in there. You and Layla would be greatly missed if you leave.
