Louise has a favorite stuffed animal, Oscar. He's a floppy-eared dog, and she's had him since she was born.* Now, however, Louise has decided that Oscar isn't a he but a she, and her name is "Rose." To complete this transformation, she's bound Oscar/Rose's ears together on top of his/her head in a sort of ponytail topknot using a little hair scrunchy affixed with a white, artificial rose.
Of course, Oscar/Rose's anatomy is appropriately ambiguous, and there are no X or Y chromosomes to tip the scale either way, but I've known him/her a long time, and I'm habituated. In my mind, he is and always will be a he. Rose looks, to me, not like a lady-pup, but like a dog in drag, a stuffed animal transvestite. And not a particularly successful one at that.
But if that's what makes Rose happy, then I'm happy for her, and I will always support whatever lifestyle she chooses.
* Thanks, Hilary.
