I must agree with that, Fuzzy, one has to learn to ignore those kind (learned by my own experience) I realize how very difficult it may be, but by not replying to their antagonism, pisses them off often, try to resist, this person is wanting you to pissed, and that isn't good for your friends to see and allows this bully to have their sick thrill.
Try to hang tough against this bullying, obviously this bully has some sort of mental issues and needs help.
Good luck,
