Okay, so you meet a couple for drinks.  They are lovely, you are lovely, everyone is lovely.   Then...drum roll....they say ..."oh look here's our son, do you mind if he joins us?"  uhhh...sure...because...va va voom....Very hot thirty something, who by the way, sits next to you.  The next thing you know the son is pressing his leg against yours, etc, etc, etc.  The evening ends.  The couple says "We would love to get together again"  wink wink.  Great!  The son says  "why don't I walk you to your car????"...uhh ohhhh.....

the rest is history.

Has anything similar happened to you?  And what would you do?
