Hermione was jealous of the freedom Ginny was experiencing that evening. At one point she almost called out to Ginny when she walked past the curtain but Cormac was close by. So instead of saying anything Hermione held her breath and prayed he didn't look down.
Unfortunately he did and the toes of her shoes peeked out as someone breezed by causing the curtain to wave. There was no where for Hermione to go to escape. Cormac had her cornered. Out in the view of everyone else, she had been polite, but here just the two of them she didn't feel the need. "Will you get you're damned hands off of me?" she demanded the silence that hung on the air after her request was shocking. Just as she'd yelled Professor Slughorn must have turned the music off in order to make a speech of some sort.
