Same with me, They say something about home keys and to always leave your hands on them, I got in trouble so much with that from my teacher last year (Mandatory class -_-) but in my opinion it slows you down, I literally typed one handed faster than my friends in that class! And 30 Words 90% Accuracy was a 100 in that class! Come on lol
Same with the pen though, I hold it between the first two fingers and the second too (I was a kid, thought that was obviously why you had two fingers sticking out and one to the site, to measure where to put the pen (Yes, I was a weird kid)) So its just stuck like that and I write different than people to this day, I tried correcting myself but it just feels weird dont it?
