My son came in from school yesterday feeling sorry for one of his teachers.
There was a different teacher taking one of the classes. She was lovely, he said. But some at least of the boys spent the class shouting and running around the room. Nothing she said would make them sit down and attend to the lesson, he said.
I don't recall this happening at my grammar school in the 1970s, but I imagine that it is the kind of thing that prompted a populist call by UK Education Secretary Michael Gove at the weekend to reintroduce old-fashioned punishments into schools. The very idea makes my insides shrivel up.
