One of my colleagues is pregnant, and I asked her how the little one's coming along.
She said everything's going great, and then said: "Did I tell you that they've said we're having a girl? At least that's what it looks like we're having". Which is kinda sweet & sensitive; after all, she recognised that the baby's genitals mean that it's probably a girl but she's aware that this can't be taken as gospel.
Then she said she had a dream after they'd learned the sex of the baby, and that I featured in that dream. In her dream she'd had the baby & was bringing it around the office to show off (as new parents tend to do), and I'd asked whether this was her daughter. She replied: "Oh, no - it's my son. We thought we were having a girl but it turns out they got that wrong and he's actually a boy".
I'm so incredibly touched by what this dream represents.
It's clear that the fact that she has a transgender colleague who has transitioned from female to male right under her nose has made her think a bit differently about gender, and as a result she's open-minded about the gender of her baby-to-be and will probably be very accepting if that kid ever needs to come out about anything.
That's how we change the world, people: one person at a time.
