Hey Mark,
As usual, you bring a voice of sanity to this forum.
Even when I was 20, 20-year-old women seemed immature to me. I was into older women back then.
Now, a 20-year-old doesn't just seem immature; she seems like a child. They say the stupidest things. When I was 20, I didn't really like to talk to 20-year-old women. Now I can't even stand to be in the same room with them. They are just in a different world.
I can't imagine how 20-year-olds are going to seem when I'm 45. I'm probably going to think they are from a different planet or something.
At 31... I'm more looking for a wife in the range of 24-28. The early end of that spectrum, 24, may still be a little young... but most people grow up a lot in their early twenties.
Even at that age, when I'm 80 and she's 72... hopefully I'll still be able to bring her water! One can only hope to be so spry!
