For a moment Severus just looked at Lily's hand on his arm. "I think it would be good to know how to dance." He stated, not sure why but he had heard that a ball was a very proper pureblood thing. He wasn't a pureblood, but a lot of Slytherins were and he had heard talk about dancing at a ball. It sounded absolutely horrible to him but if he could dance with Lily it might not really be so bad. Yes, he knew he was fantasizing about something that probably never would be.
"Have you every been to a ball?" He asked before he could stop himself, he hid behind his hair again cursing himself for that stupid question.
