Up or down, with shadow

I got up before 4 to prepare the lessons I wasn't up to doing last night. By 8, not having done everything I needed to, I was ready to resign but I went into college instead. So today I've been learning the teacherly skill of winging it. From the outside I suspect I looked quite like a normal teacher most of the time.

I am very sad to be missing a theatre trip this evening but I must now go and work on tomorrow's lessons.
