Oh, no, definitely not, haha. I think she hates broom travel. I'm still considering that Gryffindor boy, though, and he most definitely would.
And that's silly. What sort of social education are these kids getting if they never learn how to party with each other? We ought to have some kind of ball anyway. My university was divided into ten smaller colleges, and we always had a few major school-wide events to build up the sense of overall community so that we didn't end up with nasty rivalries. I think that's particularly important in this case, and it would be nice for older students to have a chance to get together with other students from other houses and years without worrying about harming the sensibilities of some nearby 11-year-old. ...Also a ball would be really fun to RP. There are always shenanigans.
