Marc: Claudia, your garden is so colourful and green. How do you keep the roses so fresh?
: I always fill the pots with soil, and water them a lot.
Marc: Is that all? This can't be! The seeds I plant never grow! I am definitely doing something wrong.
: You also need to pick up the leaves that have fallen, and trim them from time to time.
Marc: The only thing I am good at is mowing the lawn.
: Perfect! In that case, you can mow my lawn!
