I think there are some stupid people on this board.
I don't think there is any dispute about what happened to Artie's dad. And its pretty obvious his problems stem from that.
Why Howard hasn't called him? Don't know, but he DOES care about Artie...way more than he ever cared about someone like Jackie.
What would be "stupid" is believing everything that came out of his mouth. What would be "stupid" is calling other people who disagree with you "stupid"
