" What could I do? My needlework teacher suffered from a problem of vision. She recognised things according to expectation and environment. If you were in a particular place, you expected to see particular things. Sheep and hills, sea and fish; if there was an elephant in the supermarket, she’d either not see it at all, or call it Mrs Jones and talk about fishcakes. But most likely, she’d do what most people do when confronted with something they don’t understand: Panic. "
