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.
