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?

A nice thought until you run into a left handed thread…
And you feel so incredibly dense every time you run into it and you can’t figure out what’s going on. The crank on my kids bike was out of whack the other week and I kept tightening it down and it kept coming back loose. I was turning the crank one way to tighten it which was pushing it against the lock nut but it needed to turn the other way to be pushed against the bearing before I tighten the lock nut down. If it was all right-handed it would have been clear what I was doing.
It’s works most of them time unless you’re in a specialty trade making spindle, gears, and such that must be threaded backwards to avoid the wheel undoing itself.
Or you work with gas cylinders.
I don’t understand this one, please Airgas
Reverse threads on gas cylinders are (as far as I know) only used for flammables.
I was sure there was a reason, I just never worked in the field long enough to learn or ask why
Thanks 🫡
They’re made that way so you don’t accidentally connect a gas cylinder to a water line.
Fucking facists keeping me from tap en flambé; like they know what is safe.
