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.
I guess because people under 20 type like illiterates that if you type correctly, using proper punctuation and spelling and what not, they assume you have to be older.
I had to read this three times to make sense of your grammar; so now I assume you’re under 20. ;-)
I don’t want to agree. Also, I often agree.
