Sometimes there are subtle signs that I could never be a writer. One of them is my response to the question about what a T grade is, and which I see no reason to alter to provide any real substance:
T is for Troll. It's below Dreadful and Poor, so you must be really stupid to have managed that.
I'm sure that's just what Chris RObertson would want to hear.
I see absolutely nothing wrong with that. Then again, all I'd have had to do was sign it with Niffler and no one would have questioned it. Except the crazy people who've never read HP.
