Yeah, I stuck my foot in my mouth.
For information's sake, I own both Memento and Inception. I really like those movies. I think they're great, well-made, interesting movies. I just don't like watching them with other people, because much like I don't enjoy the inevitable "blue dongs and haha, you remind me of Rorschach" discussion after seeing Watchmen with someone, I also don't enjoy the "let's get up to snuff on mechanics and use this opportunity to make others feel bad" discussion, much as I don't enjoy the "let's look at all of the things that were factually wrong/stupid or imperfect worldbuilding" just after reading Harry Potter. They're the easy nitpicks, the easy social opportunities to say something without saying anything, and they really drive me bonkers, like when someone makes fun of my stutter or similar instead of actually discussing whatever about me is bothering them. They're easy ways to deflect, engage, and make yourself look good. They're all ways of cutting down what you see rather than positioning it in a good light, rather than continuing to enjoy it.
Maybe this is all a long way to say that I'm socially exhausted, which I hadn't really known yet. Sorry. My roommate is wearing me out, one of my math classes is absolutely full to the brim with jerks, and I had a girl really try to eat me alive last Saturday. And I guess I'm kind of lonely, in that "need to talk but can't communicate" sort of way, kind of like I end up hungry but can't force myself to eat enough right now. The way I talk about myself is by talking about what I know and what I want to find out, but there's no one there to do that with. I wear people out. One of my only friends here didn't even say hello with his eyes when I saw him the elevator the other day. On the other hand, he was talking about model theory avidly, so I guess that it was pretty fair.
tl;dr: I'm stupid, ignore me.
