Ron: This is mad! At this rate, we'll be the only ones in our year without dates! Well, us and Neville.

Harry: Yeah, but then again he could take himself.

Hermione: It might interest you to know that Neville's already got someone.

Ron: What? Now I'm really depressed. Oi, Hermione... you're a girl.

Hermione: Very well spotted.

Ron: Come with one of us! It's one thing for a bloke to show up alone, but for a girl it's just sad.
