The world has a lot of different standards for a lot of things, but I have never heard of a place with the default screw thread direction being opposite.
So does each language have a fun mnemonic?

Shit, a standard thread feels natural to me, but a left hand thread still fucks my life up sometimes — trying to notice what’s going on before I strip it.
My grill can connect to those camping propane tanks, but it’s threaded opposite… gets me every time
I think it was old Chryslers had opposite lugnuts, I can only imagine how many stripped threads happened
I have left-hand threaded fittings on a few things and always say to myself aloud “This is reverse-threaded” before I attempt to turn them then still fuck up first turn. It doesn’t stop me from fucking it up the first time - it just helps me remember why.
When I train new people on this equipment I tell them to say it aloud, show them, still fuck up the first turn, then they laugh.
Then I have them do it in front of me including saying it aloud - and they fuck up the first turn…
When you’ve been doing something unconsciously for decades it’s really hard to break.
