“You’ll be on your knees by half term” a teacher told me today. I’m not sure if she meant exhausted or begging to keep my job. I seem to be in constant motion, if I wore regulation male teacher clothing I’d resemble a beige blur. I’ve developed a kind of speed walk, not fast enough so I could be accused of running in the corridor and setting a bad example, but a kind of lolloping quick step powered by my long, rangy legs. I’m beginning to suspect the teacher in the opposing classroom thinks I have a daily case of the runs.
