She remembers one phase, when they were, what? Four, five, six, seven? It went on for a while. They’d decided that all the characters in every story had to be female. Winnie the Pooh was female, Piglet was female, Peter Rabbit was female: If Roz slipped up and said “he,” they would correct her: She! She! they would insist. All of their stuffed animals were female, too. Roz still doesn’t know why. When she asked them, the twins would give her looks of deep contempt. “Can’t you see?” they would say.
– Margaret Atwood, The Robber Bride (1993)
