Does each language have "lefty loosey righty tighty"?
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.
You know this has always confused the fuck out of me. You are going around a circle, how is there left and right? There is up-and-left, down-and-left, either way is left. If I am starting on the right of the circle (assuming I'm looking at it) which way is right? Up or down?
This has always annoyed me too. I know why it works, but it's clockwise and counter-(or anti-)clockwise. If you were turning from the bottom, left and right are mixed up. Maybe it's just too hard to come up with a phrase using those terms?
Use right hand thumb rule. There is no right, there is no left, there is no clockwise or anticlockwise. All of them depend on the way you looks. Rught hand thumb rule fixes it for humans
