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.
@magnetosphere I feel like society imposes way too many rules that don’t make sense, hence they cause lots of misunderstandings like this. I’m not sure if it’s the English graduate in me or what, but I always write on the Internet as though I was speaking to someone, and I’ve never really thought about it, although I’ll be honest and admit my own guilt in criticizing other people‘s writing styles. But that’s more the English grad side of me, not shutting up I think.
