Albus mock-gasped and threw a hand over his heart. "You pain me. You can't take that away from me. It's the only thing I'm looking forward to when my birthday comes around!" He grinned at her.
"Lily-Lu," he complained. "You're so little. Mum and dad would kill me if I let anything happen and you were drunk." He knew he was being silly. She was old enough, even as a couple years younger then he remembered her being. But he wasn't sure he wanted to see what his sister was like when she was drunk, or even just tipsy. It was a big brother reflex, to not want to see her dancing on a table or something of that nature.
To change the subject, Albus pointed over towards Fred. "See who Uncle Fred is with? That's Helena Ravenclaw. And I'm pretty sure he fancies her, just wont admit it to himself, or anyone else." He chuckled again. "He just told her she looks good in her pants," Albus explained further, and what his laugh had been about.
