To Bust, or Not to Bust? (Not talking boobs)

[NashVegas]

Okay. Say you worked in a certain industry and came into contact with a guy who saw you in a position to do him a favor and he worked you a little. Not overboard, just enough to make you *suspect* he was full of shit but keep the jury out 'til it was confirmed. Then one day, shortly after you've decided he was indeed full of shit, you land on his MySpace page and see a comment post from another woman, also in a position to give a career assist, who apparently took a line he also gave you (which you, smart girl, did not take remotely seriously) and made reference to it in her post.

Do you behave and just walk away? Or do you have a little fun and post right on top of hers, with your own reference, and skip away giggling?
