But like all things, it has its perks. The kids are generally happy to see you because they believe that your presence indicates a lighter workload, and they tend to forgive you if it turns out they're wrong. You can make lame jokes that confuse the hell out of everyone, without worrying that your perceived insanity will hurt your ability to educate properly in the future. And if the teacher decides to softball the lesson plan in his or her absence, you get to watch children watch movies!
Oh, and sometimes there are bunnies.
Apart from an improvised review/lecture on scatter plots and some homework help, my job on Monday morning largely consisted of keeping the room quiet and focused while Bill Nye rattled through the glorious history of genetics research. Since the kids were pretty well behaved, I mostly just paced from one end of the room to another, looking responsible. Curie, meanwhile, would chew on stuff constantly. I don't know if that improves the learning environment, but it definitely made the room more awesome.
I'll be honest: this entire post was cooked up for the sole purpose of posting a picture of a rabbit on the internet. Is that so wrong? I don't care. You'll thank me when you need your bunny fix.
