Everything I need to know (about love) I learned in kindergarten?

In the past few months, no less than three guys I went to elementary school with (and really haven't seen since then) have resurfaced (thanks, Facebook!) and asked me out. They are all nice, normal guys, so of course I say yes - it's just odd. Wondering if there's some sort of dating site out there for people you haven't seen in like 30 years - because it could very well be a treasure trove. The weirdest part? On the whole, we all look pretty much the same (thanks, Botox!).
