The spelling thing bothers me a lot. I don't want to catch bad habits of writing shitty just because it's whatever seems trendy at the moment.
People used to give me shit for not using smileys, so I started adding :) everywhere in text messages. Then people told me I seem passive aggressive because I use :) instead of emojis.
Joke's on them. I could never be arsed to use emojis outside of very specific contexts, and now gen Zs are making fun of them for looking like boomers with their dumb emoji use. Apparently I still come across as passive aggressive though.
