From somewhere, Rosemary has developed the idea that everything is replaceable. If she drops something, breaks something or loses something, she says 'Never mind, we can buy another one.' If we've run out of noodles or oat biscuits, she will say 'Maybe we can buy some more.' If she sees a toy she likes at her nursery school or at Parliament, and she's told she can't take it home with her, she might say 'Oh OK, maybe we can buy one for me.'
Perhaps she thinks she can single-handedly bring the economy back into gear.
