Yes. Best not to let this... get out of hand. It was nice, the way things were. They had fun together, even if she was fond of blaming him when some small detail went awry. There were certain girls you could tumble into bed with and have it make no difference, but that didn't quite seem to be the case here. It would change things. No sense it mucking it up. That didn't mean, however, that he couldn't take a bit of pride in the way Amarissa had become a little... Merlin- flustered? Well, that was nice, if he did say so himself.
"Yeah, I think I'll manage alright," he bemusedly replied, his backward footsteps carrying him to the door.
This would be fine. He hadn't done anything completely ridiculous. And the next day they could just act like it hadn't really happened. Drunken kisses were things easily excused. And besides - it was Christmas. Everyone was a bit more affectionate when they were feeling festive. Hell, he was pretty sure he kissed Sirius on Christmas- not like that, of course.
He chuckled a little as his hand found the door.
"Merry Christmas," he bade with a final grin before he slipped outside.
