Oh, please.

Yes, I'm the meanest teacher in the world. I assigned you homework in advance of a field trip. The fact that the vast majority of you need to do a little research to understand just what it is you'll be seeing in Seattle next week is unimportant, I suppose.

(Translation: If I get any further visits to my office today complaining about the aforementioned homework, I'm... assigning more. Yes. That.)
