You are more likely to find three TVs inside a randomly selected house than you are to find a single book that is or was not read to pass an exam, to please God, or to be a better cook.

I'd hoped for someone who was remarkably intelligent, but disadvantaged by home circumstance, someone who only needed an hour's extra tuition a week to become some kind of working-class prodigy. I wanted my hour a week to make the difference between a future addicted to heroin and a future studying English at Oxford. That was the sort of kid I wanted, and instead they'd given me someone whose chief interest was in eating fruit. I mean, what did he need to read for? There's an international symbol for the gents' toilets, and he could always get his mother to tell him what was on television.
