I wanted to make a post on this because I still do it when I’m writing fast and I hate it lol. I took a Japanese language + art history class for a semester in college and I can still hear りお先生 scolding students for doing a lil curve when writing some kana. It’s apparently natural to do in english because of how we write our alphabet or something?? Anyway, she made sure we all knew the proper way was to do it with the curve heading downwards, and not doing a lil 〜 action. Whenever I mess up I grab another notebook and practice writing it the ~proper~ way ten times!
