There's also the type that constantly has extra (possibly clarifying) thoughts in the middle of their typed sentences. So, they use parentheses to add those clarifications because having to retype the sentence would derail their train of thought and they'd then completely fail to convey anything.
I absolutely detest that kind (the kind who writes a giant parenthetical in the middle if their sentence before one or two words at the end. Just put the fucking parenthetical after the sentence! jfc) of person.
So, so much. Then realizing you typed two paragraphs replying to a text. Then spend 30 minutes on full re-edits until your self doubt makes you eventually delete it all and simply respond “ok” where normal people only take 10 seconds to type that and yet you get annoyed by their lack of communication. And thus the self hatred spiral continues, as ever.
