My old person trait is that I'm unreasonably annoyed by people who don't write in full, correct, complete sentences, punctuation and grammar included.
Something interesting I've found is that people use 'lol' to show disinterest or mock the person they're replying to, not to show amusement. And that's not the kind of person I really want to engage with.
I can't speak for everyone, but when I say lol I usually am trying to soften a self disparaging statement or expressing the absurdity of the situation... Or just lighten the tone because I feel like my message is too serious and I'm coming off like an asshole
It isn't a hard and fast rule, just an observation. For some, it is just an interjection, and that's undeniable.
One weird thing for me is that I came online in the brief era between when simple smiles, the old colon parenthesis, were a thing but lol wasn't yet. Habits already defined, I guess.
i find uppercase letters useless most of the time, because having two symbols for every letter seems kinda redundant to me? also it looks way cleaner for me that way.
especially the 'I' in english is horrible, just use 'i'.
That's all fair. All of my shit is a me problem, and I try to not judge. I'm in a corporate job and all the terrible grammar and spelling is just rampant there. So it's not like I can expect it everywhere online.
