Dominic thought about that, though he didn't have many Slytherin friends. Certainly, none he'd had to give presents to. "That sounds... appropriate." He wasn't going to say it was because Slytherins gave the impression of only really trusting one another, but it was going through his head. "Gryffindors, though." He thought of Seamus and Dean and Ginny and Logan's brother Oliver. "They all seem a bit Quidditch mad. Maybe they give each other tickets."
It wasn't really a serious sort of conversation, so Dominic smiled. "When did you graduate?" he asked, aware it wasn't always the best question but wondering if they'd overlapped at school.
