If you watch a lot of movies and TV shows more than once you might not have as much time for teching as you would otherwise . . .

If you’re good at teaching, you’ll care more about the differences in the kids from year to year, surely?

Don’t worry, the politicians keep changing the rules of what to teach and how: no two years are the same.

If you get lots of repetition in your day job, wouldn’t you want lots of novelty in your spare time?

Are you interacting with a classroom full of students who you know as you teach, or lecturing to a camera?
