Q: Help me find my buddy!

Q: In honor of Olof Palme’s birthday, January 30

@Avi In mathematics (more specifically in the variety of "abstract nonsense" known as category theory), a co-X is like an X but "with arrows reversed": if X involves functions from A to B, co-X involves functions from B to A, etc. So a co-bee would do all the same things as a bee, but backwards.
Paul Erdős joked that a mathematician is a device for turning coffee into theorems. So, say the category theorists, there should also exist comathematicians, who turn theorems into ffee.
(And if you're thinking that they've spelt that last word wrong, I think that's part of the joke.)

@GarethMcCaughan coconuts 🤔🤔
watch out folks, drinking juice from co-co-nuts might induce co-nfusion
co-co-nuts: juice -> co-nfusion
co-nuts: nfusion -> juice
not sure if that's how it works tbh
I'm sure you can make a great puzzle out of this if you think hard enough; unfortunately, I happen to be too busy nowadays to do so :(
