if I get the slightest dickhead vibe off a guy my tendency is to immediately:
1) Fix my lipstick. (self-validate)
2) Start packing my suitcase. (prepare to exit if boundary is crossed)
Now that is a classic MJ answer. Love it!
Ok, gotta go put the kids to bed, make myself and H ice cream sundaes, and settle in for Lost. ...and maybe have sex. We'll see. But the sundaes and Lost take precedence.
