Homework Hell

My middle schooler is still up. It's 9:51 p.m. and she hasn't done her math homework yet.
Instead of making her stay home and get it done, I let her and her friend head to the store to buy things for their Halloween costumes. Of course they got back later than I anticipated. And now she's still up.
It's not that late, you say. Oh, yes, it is! Particularly if she has to be up at 5:45 to shower, dress, eat breakfast and actually make it to the bus stop on time! Nevermind that she's keeping me up, too-- and I also have to get up with her at 5:45 just to make sure she gets out the door.
Luckily, academics are fairly easy for her. Like her mother, she loves to be busy and is constantly signing up for activities she just doesn't have time for.
I don't remember having as much to do as she does, though.
I made it out of middle school and high school, and did OK. I'm sure she will, too. In the meantime, what is she still doing up?
