A tiny joy of gender ambiguity: children construct the most endearing descriptions. My daughter confidently informs me that I am a boygirl. Another child tells me that Captain America is a girl who likes to be a boy. A third tells me that some dads can be girls because girls can marry girls and one of them can be the dad. They do seem to attach importance to the amab/afab distinction, but they're totes fine with complex mappings onto masc/femme identities, roles and presentation. It's sweet.
