Would you do it? and why?

An undergrad came into lab today and wanted to have a discussion about this article on cnn. It isn't really that all that new or ground breaking, except for the fact that he only wanted to talk about because he thought the teacher was really hot. That then got me thinking:

If you are 28 and fairly attractive, why would you sleep with a 13 year old?

We were only able to come up with a few reasons:

1) the kid is some Freddy Adu-esque sports phenom that is (or already has) gone pro.
This seems unlikely coming out of McMinnville, TN.

2)given all the growth hormones that are in Chicken McNuggets and other processed meats, the kid is probably 6'8" and weighs 300+ lbs. and she wasn't aware of his age.

3)she didn't think he was 13 because the average age for a 7th grader in McMinnville, TN is about 19.

Am I missing anything else? She was even married at the time! I'm not the cheating kind, but if I were going to, especially to get back at or hurt someone, it would be with a Dr. or supermodel, or something, not a kid. We all saw how the case like this in Washington turned out. The lady ended up having two kids, and now they all live with the kid's parents becuase the boy dropped out of HS and no one will give her a job. It's weird how this situation can turn that boy into every other middle school boy's hero, and her into a wretched stain on society.
