Paul and Wendy are talking about the Amish.
P: What do you plan to do in the summer, Wendy?
W: To be frank, I haven't made any plans. What about you?
P: I'm thinking of going to Indiana.
W: What on earth for?
P: To tell the truth, I want to see how the Amish people live.
W: What for? From what I hear, they're boring people. To be honest, I think they're kind of weird.
P: Nonsense! In fact, their simple way of life is quite appealing to me.
W: Well, to each their own, I guess.
P: Exactly, I wish more people would just live and let live.
