(My daughter is eleven and owns a teddy bear. His name is Mister.)
Daughter: “Mom, Mister is seriously considering a sex change.”
(I am surprised, but don’t let on too much.)
Me: “Oh, really! Why does he want that?”
Daughter: “Well, because the female teddy bears can have so much more clothing. They can wear a lot more different and cool clothes. Mister thinks it would be really cool to have that. And then his name would be Missy instead!”
Me: “That makes sense. And teddy bears really only have social gender, they don’t have juridical and biological sexes like us humans do, so I bet it’s a lot easier for a teddy bear to switch genders than it would be for a human.”
Daughter: “Yes! I just throw him in the air and shout ‘Hallelujah!’ and that’s that.”
(After spending a day or so ‘seriously considering’ it, Mister did indeed become Missy.)
