I think I just one day decided that the long term consequences, especially at work, were not worth the energy expended. Besides, it made them think I cared enough to be that angry, when in fact I did not. It was almost like a mental exercise for me. So, I decided not to react that way. Sometimes silence is the most cutting.
I wouldn't worry about being apathetic. That is psychobabble. If you don't respond to that and a shrink doesn't know you are AS or something else, they would say it's self confidence not to care to that degree about the opinions of others. It's find to acknoweledge if they bring up something you really should change, but really, why bother to cut them to the quick otherwise?
