Why do married men want affairs with much younger girls?
Probably because young girls are naive, more fertile, and they make the men feel younger. That's my guess, but regardless it's not right to cheat no matter what.
What sort of things do you do while the TV is on (apart from watching the TV)?
Obsession with how to behave based on gender. Regardless of your gender, you should be allowed to wear, play, or act in whatever way you wish (as long as it doesn't harm others) without judgment. Definitely when it comes to children.
I don't really have a favorite decade for movies since lots of my favorites came out different years. Though I do enjoy older horror movies because they left more to the imagination.
