I watched Fatal Attraction last night.

[undeterred]

15. I think the Dan character that Michael Douglas really displays the way men rationalize affairs...

especially in a situation where the man is in a happy marriage with a lovely wife and child. The only real reason he cheats on her is that the opportunity presents itself. He's not the least bit unhappy or lonely.

The woman he picks is attractive but it seems to take him by surprise when she asks him "what are you doing here" and expects him to spend time with her the day after sex. When she starts calling his office and his home he's kind of horrified that he can't contain it. But it really isn't that shocking. The whole thing starts from a "date" and the expectations are kind of ambiguous. Well he knows what his are, but he doesn't imagine that hers might be different.

Then when he finally has to tell his wife about it, he says the usual "it only happened once" and "it didn't mean anything". But it means the whole world to his wife.
