I can relate to most people, but the way that I usually relate to people me age is in the "I remember going through that a few years ago" way.
Most of my time is spent with those who are significantly older than me. The way my life has gone it has just ended up that way. I went to college four years early, and I play Ultimate Frisbee, which is still predominantly an older scene. Also I travel a shitload and have significantly more life experience than my age would attest to.
Of course, there are always those people that you click with and form an immediate, intimate bond with. For me, those people tend to be my age or just a few years older or younger. Because no matter what any of us may think, we aren't as mature and unusual as we think, lol, thank god :-) There are always others that can keep up. You just need to find them :-)

Bisous,
Silvie
