I've got a friend who became inactive and whenever he'd go to a family function where they'd pray over food someone would always pray that "Chuck" would find his way back to the church. "Chuck" finally told them that if they mention him again in their prayers at family shin-digs he and his wife would never come to dinner again.
Actually, what really got under my skin was my Grandmother's (my father's mother) funeral when 4-5 people got up and talked about how great it would be if we could all accept whatever it is we should accept so we could all be in the celestial kingdom together and how horrible it would be for just a few people to mess it all up (I'm paraphrasing and ignorant). I was 14 and it was my first funeral and I left pissed.
