See, it's interesting because that's the sort of thing I want to avoid, Patr/Kati. My last major relationship was sort of from that need, as well.
What's interesting, though, is that there was another girl I met recently: another student intern at the school I'm interning at. I've been driving her home at the end of the day just about all this week, so we've gotten to know each other. And I was trying to decide if I really liked her because she's a nice person (which she really is) or if it's because I'm tired of being single. We don't really have a lot in common and while we're friendly with each other, there isn't a lot of chemistry.
With this other girl, though, there was chemistry. In fact, it felt like it built throughout the night as we further gamed. At the end of the night, when I was getting ready to leave, I was talking to another friend about my student teaching and particular troubles I was having with one particular student. The girl seemed to be listening to the story very intently. Normally, that would just be, "Oh, they're listening to an interesting story about a struggling 5-year old," but with her, it felt...different. Like she was impressed that this guy she's listening to is teaching such young kids.
I'm strongly resisting the temptation to message her on FB today and invite her to a movie tonight with some friends (previously-made plans to see possibly The Expendables).
