As a teacher, there is no such thing as a boring, routine day. Sure, the madness begins to feel more routine after a year or two, but I'm assuming any time you work with people... there will never be a real routine. Granted, there have been times where people ask how school is going, and I've been guilty of answering, "Oh, it's the same." But I don't usually clarify that "the same" means "totally unpredictable."
For example, today I smelled a girl's boot to verify if, in fact, it did "smell like cat pee."
