Busy... but mostly just lazy

I would love to write about how busy I have been with my student teaching and how when I get home I'm just so exhausted I grade papers and then crawl into bed. And that's why I haven't been writing much.
That would be true, except that it's not.
I'm doing my student teaching, and it keeps me fairly busy, but I'm just teaching occasionally, and it doesn't involve a lot of grading. That can't be it.
I haven't taken any pictures this month, because our camera has fallen under the couch. I know exactly where it is, and I could reach it if I ever got down on my knees. But then I know the battery's dead, and that would mean I'd have to get then off my knees, run upstairs to charge the battery, and then wait for the battery to be charged before I can use it.
This is also why I haven't used my cell phone in a few days.
Man, something's got to change! I can't keep up this laziness.
