You exist to be silly, your place in existence is to be challenged. The grief and reality is here to challenge your silly. You know you’re doing it right if you’re a sad clown at your grandpa’s funeral, when he (a) hated clowns, and/or (b) loved clowns. (Your family will despite you for a year, then never stop laughing about it.)

Roses are red
Earth is an orb.
Nevermind the work,
DEY TORK MAH JORB!

The greatest measure of our society’s most tragic failings is that I can’t just get on a train/boat asap to give you a hug. Fuel ain’t free and community doesn’t benefit power, so by neither measure can I afford the day(s) away for affection.

And thus does the loneliness pandemic deepen.

How we express math is particular to us, though it’d be commonly decipherable. Math is more and more globally standardized as more of it gets globally acknowledged as “the most useful” way to do math. E.g. place holder 0 vs Roman Numerals. Ratios are conceptually universal to any species that bothers measuring. Quantification maybe less so. Especially if their comprehension of advanced sciences/engineering is somehow intuitive instead of formally calculated.

If a space faring species has a concept of proportions/ratios, but not individual identity of numbers, presenting Meters as a portion of the speed of light might be a universal way discern the rest of our math. Water as Liters might be more accessible, depending on how they think of water.

Sets and Axioms are purely conceptually representative and so viable as long as they’re capable of symbolic abstraction at all.
