Arbeitsbuch --- Stefan weiß mehr als er glaubt.
	Stefan is in the office of Frau Schulz
Stefan	Good day, Frau Schulz. Do you have a moment?
Frau Schulz	Naturally. What is it?
Stefan	I didn’t understand the last chapter in the German book.
Frau Schulz	What didn’t you understand then? Did you read the whole chapter?
Stefan	Sure. I always read the whole chapter.
Frau Schulz	And did you do the exercises?
Stefan	Yes, well … no. I didn’t have much time. I was still working on my English course, read a whole novel, did physics homework, and studied for a test in art.
Frau Schulz	Stefan, you need a day with 30 hours. What didn’t you understand then?
Stefan	The perfect.
Frau Schulz	Well, one uses the perfect when one speaks about the past. For example: When I was a kid I played with my friend (f). For my birthday I received a little cat.
Stefan	I have also always wanted a little cat. Unfortunately I never received one. But I sometimes visited my grandparents. They had a dog and two cats.
Frau Schulz	Stefan, you use the perfect entirely perfectly.
