You pick up the car at the airport, get the key and still have one question: When do I have to return the rental car?
In the story the member of staff bends down and finds an egg (when do I) that is as light as a feather (have). He wraps it in a huge blue cloth on which a sailing ship makes a turn (to return), and in the armchair on deck you see the reindeer in the valley at the cardboard table again (the rental car) – the image from the previous lesson simply comes back into play.
