Hey Underground..I've been there...I think I know what you mean... I sometimes say really rude things in the spur of the moment, without thinking it through... and tell myself "I'm just joking around", but if someone had done the same thing to me? it would really piss me off.

Of course, even we people with narcissistic traits know that sometimes people just need to be put in their place.... and sometimes anger and challenging are appropriate... it's just hard to work out exactly when and where....
