@sarahbecan If only "rightie, tightie, leftie loosie" itself had any utility and made a scrap of sense. Try it on a selection of folk and all you find is that it engenders as much confusion as it tries to solve, and exists and perpetuates as a meme only because it's cutesy wootsey childish rhymey whymey.

We were taught and teach the right hand rule, visually with a the right hand in a thumb up, explaining that a turning in the direction of you fingers, from base to tip, will move the screw/nut in the direction of your thumb.

Now this works, no matter where or when until you find a left hand screw, but surprisingly enough, if you suspect or know you have one (and there's at least one on every bicycle, usually 2) you just use your left hand and have the same result.

And this works when you're under a car, upside down, looking from behind, and whatever angle you're at. Point your thumb in the direction of desired travel and you have the curl of your fingers to tell you the turn direction.

How does the cutesy wootsey meme fail everyone, always? Because turning is clockwise and counterclockwise, there is no right or left turn, never was, never will be, and so the student needs to remember a newly invented mapping between right and clockwise. And even that fails when approaching from odd angles (tightening something from behind) and clockwise/anticlockwise is of no use to the working mind. The right hand steps in and voila.
