OK, what is it with me and guys in their thirties?

I have a radio show here at my university. Actually, I have two shows, one in the morning and one at night. Well, a guy named Ron--who seems really cool, really nice--happens to be a fan. We've talked on the phone a few times, particularly on Tuesday and today, and he's making me a mix tape. Well, the thing is, he's 35 and I'm 21 (almost 22). I don't have a problem with the age, and I'm not even saying there's any sort of sexual or romantic element which will grow out of this. But for some reason, he is the latest in a string of thirtysomethings who befriend me (and sometimes more than "befriend"):

  • 1997: Bob--36
  • 1999: Tim--36
  • 2000: Tom--30
  • 2000: Jimmy--30
  • 2001: Marc--31
  • 2001: Ron--35

and of course the infamous case of my acting professor, who just turned 39, as recounted in my February 20, 2001 node.

This is only a sample. Why? What is it about me and guys in their thirties?
