I'm 33, and my experience has basically been the same as the GP. Past a certain point, you never see your friends again unless they're accompanied by their SO, and once they have kids, their lives revolve around their kids and nothing else. And I'll always remember the culture shock when I a new job where my coworkers were mostly in their 30s while my coworkers at my last job were all in their 20s. Office conversations at the new company mostly centered on the logistics of taking out a second mortgage, debates over what kind of grass to put in their yards, and talk of what their children are up to. I was 30 at the time, and I decided then and there that these were people I had nothing whatsoever in common with, and if this is what I have to look forward to as I get older, I don't really want a social life anymore.
