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.

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.
