As far as the first thing goes, I used to avoid using any text speech at all, only used proper punctuation, always made sure my grammar was right. People started to get really annoyed with me because of it, telling me I was being overly formal.
As far as the second thing goes, that was a sarcastic joke about how the "rules" I'm told to follow are always full of contradictions, making them hard to follow. The joke being if autistics made the rules they'd be actual rules, and efficient ones. I'm well aware of why it's not actually that way.
