As a (hopefully) good teacher, I try not to let on when I'm feeling crabby or when my students are driving me insane. However, my perception and reality are not always one and the same. All of my students seem to have consumed several gallons of Red Bull immediately before any class with me this week, and it is grating on me. I hadn't realized how irritated I was, until one of my students started looking like she was possessed-- staring straight ahead with only the whites of her eyes showing. I asked what was wrong and she said she was trying to make her eyes look like mine. Apparently, I had been rolling my eyes with such abandon, that she thought I was purposefully trying to look like I was having a seizure of some kind.
