I could have written your post (except I have no confusion when someone tells me to turn left or right) . I write, eat and shave left-handed. Most other things I do right-handed. I think they call people like us “multidextrous”.
I have never heard the term multidextrous before and that makes more sense.
I have a terrible time turning screws! I’m very mechanical minded and always dread screw turning. :-)
When we go places in my truck and I’m following the GPS and the GPS lady says take next left, when I turn on the right blinker I get the “your other left” snark from the man copilot in the seat next to me. ROTFL
