the worst is when people say "i'm sorry.. but you ..." and go on with an excuse of why they acted a certain way, because of what YOU did or said. It tickles me.
OOOh I know about this, a story was once relayed to me where one person suggested to another to appologize for disrespecting this one individual... rather than actually appologizing the perpitrator went on to say
"I am sorry... I'm sorry you're ugly and I can't help you there." it was awful. Totally rotten :-o
