Private
Everyone will be dead someday. In 2016, where you are from? I am most certainly dead. It isn't at all pleasant to think about, so I try not to. You have a second chance, to not be dead, and not many people get that.
I'm not supposed to use slang, either. Here I don't even understand what people mean half the time. It's tiresome. 'Cad' is a perfectly ordinary word.
Then we have a deal. It's only fair that I point out that if you mean to try to trick me or get me sent to prison I'll transfigure you into a creature. And not an interesting one. I don't think that you do have ill intentions, but it seems only sporting to give a fair warning.
