When Mari came home, she found a parcel outside the door. She was not expecting anything, so she looked at the name. The parcel was for a neighbour in the same building. Mari went to the neighbour's flat, but nobody opened the door. She wrote a short note and put it in his letterbox. In the note she explained where the parcel was. Later the neighbour rang the doorbell and asked whether he could collect it. He thanked Mari and told her that the parcel contained a gift for his mother.
