It has been three weeks, and I am already tired. Yes! I’m three weeks into the new high school semester, and I can feel new gray hair growing. I should be annoyed about it, but it’s the opposite. I’m happy. Elated, even. I’m back with my students – old and new – and I’m teaching old and new material. But teaching isn’t the only thing that causes more gray hair to grow. A lot more, actually.
