Being able to write left handed without making ink smudges is a big reason why I now prefer digital notes. G2 gel ink is mostly okay, but I think fountain pens are out of the question for most left handers.
Alas, I wasn't taught it while neuroplastic, and have been unable to get the hang of it. I regret that my teachers were clueless about the peculiarities of lefthandedness, but at least I'm not of the era when it would have been beaten out of me.
