I am visiting my old school alone, in the middle of a period. I walk upstairs, along the Social Subjects corridor, and notice strange things behind the doors. It seems that Radio 2 is being broadcast from studios inside the classrooms. I continue down the corridor to a dead end and a door marked "AHT office".
I do an immediate about turn, and go downstairs, followed by someone whom I presume to be an assistant-head teacher with whom I did not get on. I look round, and discover that it's actually my grandpa, and I'm in my grandparents' house, so I put the kettle on.
