A: That child just won't stop crying! B: It's been crying for the last three stops! A: The mother has tried feeding it already. B: I guess she can't change a diaper on the bus. A: I read once that babies' ears hurt on the bus. B: Why do their ears hurt? A: It's because of the air pressure in the bus. B: Is it like when your ears hurt on a plane? A: Well, my ears hurt, too. B: I don't think that's because of air pressure. A: I can't stand it anymore! Let's get off now. B: Alright. That screeching is getting to me, too.
