She was having fun, certainly, doing well enough at keeping up as she caught on to what was expected and went with it. In truth, she probably wasn't actually doing some of the moves quite right; should someone have been video-recording it, they might've caught her fudging foot positions in the playback now and then, subtly, sliding into place were she shouldn't have been able to... of course, it helped that her lower half was hardly visible under her skirt....

Perhaps it would be interesting sometime, if she were to simply take to literally floating around rather than attempting all the footwork one might assume went into some dance or other? But another time; this was more for him, now. She'd simply carry on so as to not hold him back, should she mess up somewhere....
