Ah-ha! I was wondering if my mad-scientist friend would chime in and wouldn't ya know, in my thinking, she's on point. When folks notice I'm doing something with my left hand, or they notice when I arbitrarily switch hands (like
@DeeAnna), I explain that I am "an oppressed lefty". Literally had my knuckles rapped in pre-school for using my left hand. I wouldn't say it traumatized me, but I do still vividly remember it 50+ years later. hmmmm - I don't recall anyone ever telling me I had a hard time with speaking... but maybe I can blame my pre-school teacher for my inability to learn another language!
Which hand I use depends on how I learn a task. If I learn siting across from a righty, I mirror them - so I end up doing the task left-handed. I throw (pottery) and cut stained glass left-handed, etc. Self-learned, I usually do tasks left-handed. I golf (badly) and load a dishwasher left handed, etc. Learning next to a righty, I do tasks right-handed. I sew and shoot right handed, but there's more to that story.
My left hand (and arm) is strongest but my right hand has much finer dexterity ETA: Thankfully, which hand to use is a matter of convenience and not something I have to think about. Thinking about it would really heighten my "analysis paralysis"!
Story time!
Our son came home with a "dominance" science project, but he couldn't tell the subject what the test was about. He had to observe someone in his household writing, eating, etc. Then step up on something (ladder/stair), step on something he placed on the ground, reach for something in the middle of a table, throw and catch, and then there was some sort of eye test. I remember all of this because with each "test" he would mutter, "this doesn't make sense", and it got really hilarious when he went drama king and threw his notebook and pencil on the floor after the eye test and accused me of somehow cheating (and truly stomped off and so then lost his video game privileges for that night of course).
He didn't really drop it until hubs came home, did the same test, and explained to said son that I was "an oppressed lefty".
Scored perfect marksmanship in USAF training...on the wrong target. I had nothing (NOTHING) on my target, but perfect marks on the target next to mine. How they could tell that's what happened I don't know, but I was so crushed because I really wanted that marksmanship medal. Since our TI hadn't shown up to march us back, the NCO in charge of the range told my dude (whatever the people are called who watch over recruits while on the range), to have me shoot again, but to site with my left eye. Bingo. Correct target, perfect marks. He gave me a pass for shooting, but wouldn't reward me marksmanship, because I had to do the test twice. Rules are rules (boooooo). I had the satisfaction of knowing I really could shoot, and that my TI would be told same, so I was happy...sort of.
