Today I've done my last exam invigilating session at the local secondary school. I handed my notice in a couple of weeks ago.
I'd stopped enjoying doing it, and the stresses of family mean that I need more 'head space' and this is a small step in simplifying life.
It gave me an insight into how schools operate and reminded me of what curious creatures teenagers are.
I'm glad I've done it, but won't miss it.
