The little things are like—how he fidgets because he can’t sit still for more than a second, or how he sits in a desk like it’s a cushioned chair, or holds his wand weirdly—with his index finger over the top, even though that seems like it wouldn’t be enough support for a powerful spell. Or how—as anyone who has ever seen his notes can tell you—he spends ninety percent of the class time doodling in the margins. Or, y’know, that he hums a lot, but is probably completely tone deaf because he sounds awful. I mean, yes, he messes up his hair—but he does it so that he looks like he just stepped off a broomstick. And yeah, everyone knows about his smile and his laugh and all that rubbish, but the really funny thing is how he laughs at the most ridiculous, un-funny jokes.
Lily Evans - Tlat Chapter 20
"You can't think—you mustn't believe that I didn't care about you. I did... I do. I've loved being with you—even the last week or so... it hasn't been grand, but I'd much rather have you than not. I like that you—you fidget all the time; you can't ever sit still. And that you—sit in your desk, like it's a big, cushioned chair... and that you doodle in the margins of your notes, and you hold your wand really strangely, and you can't sing, and... you laugh at things that aren't even funny." It was like winning. "I like everything about you, James—I'd never just... throw it away. Not on purpose."
