In my opinion, is it okay? Sure. I just don't know what a 45 year old man would have in common with a 20 year old woman.

I'm 40 and there's a girl here at work that's 25. She rarely has a clue what I'm talking about because she wasn't there for the days of Romper Room or Saturday Cartoons or when TV wasn't 24 hours a day.

So just in my opinion, it would drive me crazy trying to communicate with someone that young.
