Cougar, trap or both?

One of the stars of the movie Ki.ck-A.ss is 19 and having a baby with his 43 year old fiancee. Can you imagine the conversation in that kids house, "Mom, I met a 'girl' that I really like and knocked her I up. I want you to meet her."? Imagine his mom's surprise when he brings the "girlfriend" home and it ain't no girl but a full grown woman in her 40's. I'm sure her inner dialog would include the a lot of what the fuck is this? and that isn't a girl, and why is she with my baby? I can't lie if G brought home some old broad I would be pissed and suspicious. I have brain to mouth filter failure quite frequently so I am sure that I would make some inappropriate comment along the lines of "so was it his mind or body that you went after?". I mean really, really, really? Maybe the early 40's is the sexual prime and she needed a horny teenager to satisfy her, but at this point you would think that she would have the whole birth control thing down. Yes, I am judgemental.

What would you do if your child brought home a person that is significantly older than them?
