Re: CONVERSATIONS.
Cho would have said hi to George and Fred and Angelina and Ron at the very least and casually tried not to get herself into awkward situations she wasn't about.
Lilu came and squished all of her Uncles/Aunts' faces. Every last one. She's not apologizing. She'll talk to them also.
Luna will say hi to basically everyone she knows and anyone she runs into. Anyone want to make friends with Luna? She's great.
Uhhh Q is really just doing his best not to be in full out nerd mode, but he's obviously super excited times one million and willing to talk to whoever. I know at least he's probably excitedly pointing things out to Eliot. sjdkf.
