This is a 2-in-1 question, I suppose. I type the way I do. I’ve always typed this way, but I’ve noticed when interacting with people (not on here) that people always think I’m far older than 19. They think I’m in my forties or fifties.
Also, I tend to type using full stops, which people may think are rude. When I’m typing a full sentence, though, I end it with a period. If I say, “He’s being an asshole,” (with a period), I mean that as a fact, not out of anger. It just happens to be ended with a period since it’s a sentence.
Full stops are slowly becoming a separator instead of a terminator in colloquial chats, which I find interesting, since some scripts use an equivalent character like that
Ooh, that’s interesting. I’m not really sure what to look for here, could you give me an example of a language/script that has that?
