One morning nearing the summer holidays I was merrily going about my business during a free. I was taking it easy as there wasn't much to do, no more lessons to plan, no more marking, a nice lazy wind down towards the summer holidays. I walk into the staffroom to check my pigeonhole. I notice a yellow cover slip sticking out. Please don't be for this lesson. Please.

Unfortunately it was. I look at my watch and start walking qutie quickly towards the room. Only twenty minutes late with all the desks rearranged and kids bouncing off the walls. I've had nightmares like this. Right down to the last pencil that's been thrown on the floor.

Still, by being twenty minutes late there were only forty more to go.
