“Do you have a lot of sad things in your head?”
Perhaps he's too trusting, because when he opens his mouth the answer is "yes,". Given all of that though he still doesn't want to talk about it, how could Lily Evans ever understand? The smartest witch in her year, the one with a brain that everyone talked about, couldn't know what it was like to be him not much in the wits department and a chronically bad student.
But it wasn't necessarily because he was stupid. He wasn't entirely. He was too worrisome to be stupid he figured, somewhere along the line he'd heard an old man tell him that the more you worried or the more depressed you were the closer to reality you were. So he supposed that he was close to reality, and not entirely idiotic. Instead he was just terrified of teachers- authority figures really and he hated classrooms. Sometimes the classes weren't so bad but he hated trying new spells, some of his classmates always seemed to get them right on the first few tries and Augie was left to work on supposedly easy spells whilst the rest of his classmates moved onto harder material. So he was terrified of them, and being watched, he was basically scared of everything and by the looks of it Lily would never know that was like.
She was a muggleborn too, and he suspected that she'd heard people call her a mudblood behind her back too but the trouble was, mugglborns like Lily proved that they were just as capable as every other sort of wizard. Meanwhile, Augie did everything to prove the stereotypes right (he didn't mean to but that's just how it played out). Then of course there's his mother, she didn't really leave him he supposed after all it was his father who must've started the mess. Augie knows the birds and bees by now. But he still wishes he could talk to her, or know what she's like these days still pretty? Still a socialite? Did she ever marry? Did she have any magical blood in her family? Maybe she was a witch.
It would be awfully nice to find out he was actually a halfblood.
