A few minutes ago, I looked up from what I was doing to the clock on the wall (one which, oddly enough, I STILL haven't switched back into MST). As the time registered with me, the first thought that formed in my brain was, "The bell will ring in 2 minutes."
Well, no, it won't. It's Sunday. And I'm at home. The bell doesn't ring here.
I suspect that the sheer number of years I've been teaching has done some damage to my psyche.
