Neville was smiling, glad that Ginny's family was so accepting of him. "Thanks George... and well, hopefully it won't take too much to keep her from backing out." Nev did laugh a little nervously though, looking around for Ginny. She must still be getting ready with Hermione.
Parvati seemed to sense that little bit of nerves in him. "I know Parvati. I think it's customary to make the prospective husband shaky." George and Parvati were so good together, and were always together - he and Ginny weren't like that but he knew how it felt to want to be near her. Everyone had their different relationships.
"All kidding aside though, I'm sure I'll get more of it soon. Feels kind of like initiation, and I'm glad to have it." They all knew he was an only child and the rest of his family was either dead, dying or gone mad so, it was something really big for Neville to be marrying into a large family.
