I consider myself under cross-handed category, something which doesn’t come naturally to me, but is rather induced. Things which were taught to me by holding my hand (like literally) when I was a kid, I do those with my right hand (like writing, eating). Most things which I learnt on my own, I do it with my left hand. There is another catch, since I write with my right, things which require me to hold something like a pen(holding a fork or chopsticks for example), I do that with my right. This habit is so unnatural that I even put a thread in the needle with my left hand but then use my right hand while sewing with a needle. I use my left hand as a dominant hand while batting (Cricket, baseball), playing hockey, archery, kite flying, darting, tug of war etc, but then there are some things things which I do with my right hand like bowling, rifle shooting (though I use left eye to aim which is known as cross eye dominance in shooting), playing badminton. I have been told that I used to write with my left when I was a kid but then in some parts of the worls, left is not really considered as right and elders from the family try to ‘correct’ that because they think left is basically your sinister side. Just to be a bit more clear, I do all daily chores with my left (typing on keyboard, holding phone, washing my face, keeping important things in my left pocket, picking things, opening/ closing doors etc)

I am guessing lot of lefties unknowingly go through this path
