May: Excuse me? Do you have anything for a carsickness?
Guide: Yes, but you look fine.
May: Oh, it's for my brother. The little boy over there. He is getting a carsickness.
Guide: Poor boy! But don't worry. Here are two pills made in Germany. It's really effective. He will be just fine.
May: Thank you so much.
Guide: Take some with you next time, just in case.
(Arriving at the destination, May comes to see the guide again.)
May: Sorry to interrupt, but my brother is still sleeping.
Guide: You mean the boy who felt carsick just now?
May: Yes. It's so strange that he slept all the time after taking the pills.
Guide: Oh, sorry, maybe I gave you the wrong medicine.
May: What?
Guide: It's just sleeping pills made in America which is also very good. But don't worry. It has no undesirable side-effects.
May: I see.
