After this conversation he proceeded to ignore me, and I assumed at some point in the conversation I'd crossed some line or other and he just didn't want to risk going near the subject again. Which was frustrating, but fair enough.
Except that tonight, when I came to leave the course (it's over! Yes! I made it!) I came up to him to say "See you around - possibly at Torture Garden!" (where he'd said he occasionally goes) and he launched into "You had me figured out from the start, didn't you? Look...if you ever want to play, you've got my e-mail." and so on.
~blink~ He wants to do stuff with me. This is good. Bizarre, but good. I was so sure he wasn't, in fact, interested. Um, go me. I think. I mean, it may not end up going anywhere, but I think I still rock.
Improved my evening some, anyway.
