Growing up, I was forced to learn how to do many sports type things with my right hand even though I am left handed. Throwing, shooting a basketball, serving a volleyball, holding a tennis racket, bowling. Parents/teachers also tried to make me use my right hand for writing, but it was impossible. Things I learned on my own are almost exclusively left handed. Holding a pool stick, chopping veggies, using a mouse, hair brushing, scissors, etc.
Yeah, this is how I do it, left always has the fork or spoon. Right is only for using a knife.
Lefty here. While I do most things lefthanded, including writing, there are a couple things I do exclusively righthanded for some reason: 1) using scissors, and 2) bowling. I also shoot a rifle righthanded, but that has more to do with eye-dominance.
Scissors makes some sense, as the finger/thumb holes on a lot of scissors are contoured for the right hand.
I remember, being in grade school, and the classroom had safety scissors for use by the kids when we were doing art projects; most of the scissors were right-handed, but they always had a few left-handed scissors for the lefty kids. I tried to use left-handed scissors once or twice (using my right hand), and it was really difficult.
That reminds me. I’m 100% right-handed. Except I mouse left-handed. I have the left button configured as primary and the right button as secondary. So the mouse itself is configured as used by a typical right-handed person. I just handle it with my left.
Backstory: I’d been in IT in school or industry for a decade+ before mice were invented. So totally adept at using a keyboard and number pad. The first time I got a mouse I was doing a lot of spreadsheet data entry in Lotus 1-2-3 for DOS. I found it was a lot faster to enter numbers on the 10-pad with my right hand and use the left hand with the mouse to bounce from cell to cell. Versus the alternative of jumping right hand from 10-pad to mouse and back while my left hand idled. Hence the lefthanded mousing to this day.
Back then which button did what was fixed. So the left button had to be primary. So I still use it that way.
I can mouse right handed with nearly equal dexterity, but it’s mental work and it’s slower.
I’m mostly right-handed, but there are some odd things that I am better at with my left hand - brushing my teeth and throwing a frisbee, for example.
I can write with either, but am much better with the right hand.
I’m extremely left-handed. Only one in my family that I know of. I don’t think there’s anything I do right-handed beyond what I have to do, like drive a car.
I was born well after it was common to suppress one’s natural inclinations. Which is good, because I am a writer, and if my early introduction to handwriting was to be forced to use my right hand, I don’t know that I would have written so prolifically. I have always wondered what literary geniuses our culture missed out on because of that nonsense.
Oh, yeah. One, er, feature of being mostly ambidextrous is that i can’t tell my left from my right. 
It’s a better reason that that. When you push the finger holes on right handed scissors to close them, you are also squeezing the blades together, so they cut properly. If you use right handed scissors with your left hand, you are pushing the blades apart. I have learned to pull, rather than push, as i cut so i can use right handed scissors effectively with my left hand, but it’s a weird and unnatural action.
My kindergarten had some left handed scissors, but they were incredibly dull, so i decided to learn to cut with scissors right handed. And mostly, i do. But sometimes it’s easier to approach a thing from the other side, and it’s useful to be able to swap hands.
LOL!
Obligatory ambidextrous meme:
The person who wrote that article head deserves a medal.
I’m pretty much 100% right hand dominant.
I’d be be left-eyed dominant if I hadn’t stabbed it during a disastrous American utensil swapping session… (joking of course).
My mother is left handed, and at 77, spent most of her life being forced to comply with righties from the get go, so she’s been trained to be semi-ambi. So she mostly uses right handed tools and writes with her right, but her left is still her “go-to” hand for more reflexive movements. She was disappointed that none of her three sons were lefties, so she could tell them that it was perfectly okay to be a leftie.
Another thing I meant to include: Since my dad was a natural lefty forced to convert, he understood my situation and allowed me to develop my handedness. My mom, OTOH, probably due to centuries of cultural prejudices, make me use my right hand. They had differing recollections about it, though. My dad basically said he let me do what came naturally. My mom, however, said I didn’t show a preference so she gave me one. I think my mom engages in a bit of revisionist history on this score. She didn’t go so far as to call my left hand ‘evil’, but ISTR that her step-mother told her as much.
Yes, one of my two sons is a lefty. My daughter and other son are righties. I’m pretty sure genetics had something to do with it.
I’m right-handed but I use my left to operate the TV remote for some reason.
Right handed. I taught myself to dribble a basketball left-handed when I was a teen, which was a definite improvement to my game (such as it was).
It also changes where you have to look to know precisely where you’re cutting. When I give righties my left-handed scissors and ask them to cut along a straight line, they usually can’t figure out where the cut is. As a lefty, I grew up with right-handed scissors that I used in my left hand and simply adjusted where I looked. Left-handed scissors took some re-adjustment.
I do most things left-handed, including write. There were 5 lefties in my 1st year class, and a left-handed principal who gave us special instruction on writing. Like some other lefties here, I bat and golf right, but mostly played lacrosse left, throw and kick a football left, could use a hockey stick either side but couldn’t skate for crap, shoot rifles right, but handguns left, have Czarcasm’s issue with catching and throwing, move the mouse to either side to avoid RSI, stopped working in construction in part because too many of the tools were right-handed, (screwdrivers and hammers okay, duh, but people would often set things up so you could drive a nail easier with the right than the left hand so you’re swinging backhand) circular saws whirling death because the guards are for right-handers). Politics, left.
Same. I went an extended time with a R and a L sharpied onto my shoes.
I have trouble telling time on a dial clock as well. My sister bought be a gag gift of a left-handed clock. That was funzies.
My brother is left handed, but often uses his right hand to control a mouse - except when the villain in the computer game is REALLY about to kill his character. Then he suddenly switches over to left hand. Our family always cited this as a psychology example that in time of crisis, people always revert to what is most natural for them.
I use my right hand for finer work and heavy work, but use my left a lot on “midrange” stuff. I use the right hand for writing, scrubbing things and picking up something heavy, but for things like opening a door, sliding a chair or the like if anything I’m a little more likely to use my left.
Hard for me not to notice since I recently pulled a muscle in my left arm, and have repeatedly given myself a painful jolt automatically trying to use it. I didn’t quite realize how often I used it before.
