Niall story:
Niall: What nut did you tell me you were allergic to, Daddy?
Joshua: I’m not allergic to nuts.
Niall: Which one did you tell me?
Joshua: I’m not allergic to any nuts, Niall. Why would I tell you I was allergic to nuts if I’m not?
Niall: It was walnuts, right?
Joshua: No. You’re thinking of someone else.
Niall: Oh, that’s right! Cashews!
Joshua: Niall, it’s wasn’t me.
Niall: I’m pretty sure it was. You told me you were allergic to walnuts.
Joshua: People can be sure and wrong, Niall.
Niall: [thinks]
Joshua: Did you know that? That someone can be sure and wrong?
Niall: Yes. [pause] I’ll tell you what we’re going to do. We’re going to have a nut-eating contest. It’s like a pie-eating contest. I’ll take all the kind of nuts, and you can eat them and see if you’re allergic to them. So if you’re allergic, you should say so before the nut-eating contest.
Joshua: I’m not allergic, Niall.
Niall: OK, we’ll see if you’re allergic to any of them. If you are allergic to any of them, I’ll give you a glass of water. There will be lots of water.
