What a terrible thing to ask!
If he's not sure, how does he even know you asked that question? And if he is sure, it might mean he's crazy, and you've just pushed him over the edge. Twenty people dead, and it's your fault! How can I...I mean he, ever really be sure? What kind of monster are you, tormenting me...I mean him, that way?
Just for that, I'm burning down the first bookstore I see that carries your book...I mean, I'll burn a copy of your book...I mean...well, I'm not sure what I mean...no, I didn't mean that.
Besides, I understand Sky's posts, so what does that make me...no, wait, don't answer that; I don't want to know.
