 And so in the book, what I do, as well as talk about questions more generally, I share four questions that you can use again and again. You've just listed them. So the what question just picks up on a word that your friend has said. So, for example, if you're talking to a colleague and they say, and you happen to mention you're a Christian, and they say, oh, why would you believe in God? There's no evidence that God exists, period. Rather than getting panicked or flustered, you might just say, interesting, use the word evidence there. What do you mean?
