And then I became an adult and visited China and met actual Chinese immigrants and married a native chopstick holder. And half of them don’t hold chopsticks “the real way”. Somehow it all works out. As long as you can eat a peanut with them, you pass.
As an adult I learned that there’s also a whole lot of prescriptive bullshit that basically nobody pays attention to. The strict definition of touch typing seems like one of those. If you can type without looking at the keys, you can touch type.
Just never cared to get perfect at it in school. I would get absolutely crushed on typing tests though with the kids who actually learned touch typing. They all had piano experience and could reach the modifiers while holding on to the home row still. I still can't really do that on my right hand, its like my pinky doesn't reach.
