I Digress; or, A Riddle.
One day, some years ago, my sister sent me an email which was entirely written in capital letters. I forget what we were talking about, but I replied to her, pointing out gently that typing in caps is bad "netiquette" & is considered SHOUTING. Nothing serious, I just didn't know if she was aware of the convention.
In reply she expressed surprise that I'd pick up on this - "I always thought you were a non-conformist", she said.
