It's inevitable. A fact of life. There are beautiful people everywhere.
Ever see the movie The Last Kiss? It's the one with Zach Braff, where he cheats on his sexy older girlfriend (Jacinda Barrett), with the hot young college girl a.k.a Rachel Bilson.
Anyways, there is this part in the movie where Zach is trying to explain his "bad behavior" to his girlfriend's dad. In essence he blames his cheating on the fact that Bilson was hot. The dad stares at him for a second as says something to the effect of, "You think I've seen my last hot brunette?"
Alright, alright . . . it's probably better if you just watch the movie.
Point being, I'd rather be 40 and sexy, than hot at 25. Hot 25 year-old girls are everywhere, but stand out, sexy 40 year-olds are rare.
