In traditional stories, fairies come at night and sweep up, or sew buttons and so on. Why isn't there a fairy that comes at night to mark student work and writes my reports for me?
I have a colleague who tells me her house is always spotless at this time of year, simply because she'll find something, anything to do rather than write reports. I'm much the same - but without the spotless house. The internet is a huge distraction. Funnily enough, I don't work on short stories at this time. I'd feel guilty knowing I hadn't finished my reports. And so neither gets done.
But there comes a point where I can no longer put it off, and I have to finish them up. Teachers know what I'm talking about.
