My sister's take has been that since trans women don't go through the pain of menstruation or giving birth, they have no right to suggest they "earned" being a woman.
I mean that and she thinks Disney became woke and they ruined her beloved 90s films. I remember talking about Putin and how he said the most Bond villain thing with "you in the west believe history is a struggle between oppression and freedom, I see it as a struggle between chaos and order". Her take is history is a struggle between modesty and debauchery and we've gone too far in the debauchery direction.
I love her, and she can surprise me with her humor, but overall she can turn into Angela from the office, but she's not even religious.
So this is sheet music for trombone, you can tell by the slide position suggestions above certain notes. I assume they expect the player to have an F attachment, because 0 position is F, however the note is G, so they would need to press down the trigger to hit it (I think , it's been a moment since I've played a horn with an F attachment). Some of those symbols I'm not as familiar with.
Maybe the joke is they play the trombone, which intrinsically is a joke of an instrument.
