I recently went for lunch with some friends and we were talking about how a huge age difference in a relationship doesn't always matter. A person might be 45 years old but act 10 years younger, so it's okay if they're dating someone who's 35.
One friend said that sometimes, though, it's just gross. She has an uncle who's in his late 40s who regularly picks up 18- or 19-year olds, and it causes her some discomfort to think about it.
"You think THAT'S creepy," I said. "When I was 12 and I would go stay with my dad, I'd have to go with him to the beer parlour and everyone would ask if I was his girlfriend."
My chuckle was met with a horrified silence.
I thought I was telling an amusing little story. Apparently I was wrong.
