While I agree and am quite capable of "taking care of business" in a LOT of different ways, I don't believe it's my place to disrupt his lfe in that way. Call it karma, call it fate, whatever.
First, the girl is better off now anyway - she got a much better job and doesn't have to deal with this asshole anymore.
Second, it's too easy for things to get out of hand. Until he does something to me, I don't believe it's my place to act as judge and jury. Yeah, he's an asshole and fucktard and everyone knows it. That's a pretty good-sized albatross he's already lugging around.
Seriously fucking with him - including doing stuff to make him lose his job - won't happen unless he does something serious to me.
I just want to fuck with him a little bit, have some fun - not start a war.
