Don’t you just love broken clocks? They make the end of class seem so much farther away. Waiting for school to end is the second worst thing to wait for. The first is your own execution. Even that’s more exciting than math class. My foot taps on its own, I've noticed, when the clocks don’t work. Exactly four taps per second, as a classmate pointed out to me one spring day, when birds outside the window taunted us. They were free and we weren’t. Twenty four thousand taps per class, and then we run for the door, as fast as our legs can carry us.
