What What, in the Butt?

My level three class has a batch of new students, so the complexity of combinations has been stepped down a bit. Like, to the point that I actually feel competent. But my mixed-level class has only gotten harder and harder, so now I am stuck either feeling unchallenged or overly challenged. For cryin' out loud, can I get a level four class, please? These dead-dull en croix degages aren't doing it for me any more, and no matter how many times you tell me the sequence of a 13-step grand allegro combination it ain't gonna happen right now.
Sigh...

Sorry, I am feeling a bit shouty, tonight.
Because I... pulled my butt muscle? Or... something. Class was fuller than usual tonight so I got stuck at a portable barre which is a good foot or more higher than the lowest rung on the regular barre. So, when we were all supposed to hike our legs up on the barre... something went terribly wrong. I got through the rest of class but begged off pointe and came home early. If anything, it hurts worse NOW than it did in class.
Effing ballet, guys. What the hell?

PS: this has been a really butt-centric day for me. First thing in the morning I had to take one of my cats to the vet because she has a ruptured booty gland. Well, at least I don't have THAT.

PPS: Look. I am REALLY REALLY SORRY, this is in terrible taste, but I seriously have this song stuck in my head now, and I am sharing it with you because I am basically a bad person and I'm going to hell (and I want you to share in my pain):
