" 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.
What constitutes a problem is not the thing, or the environment where we find the thing, but the conjunction of the two; something unexpected in a usual place (our favourite aunt in our favourite poker
parlour) or something usual in an unexpected place (our favourite poker in our favourite aunt). "
