I worked with another logger years ago, who had a firm rule about drooling over girls.
They had to be older than his daughter.
I feel a bit the same way, even though I don't have kids.
Looking at an 18 year old girl in underwear makes me feel like a dirty old man. ( Which I am, absolutely, no doubt!)
I mean, I like and love women, but with a girl that age, even communicating would be a chore.
So I find myself looking more at the nice looking ones at around my own age, these days.
