It's late at night. Mark is sitting on his bed and he is looking at his clock. His neighbours are making a lot of noises and Mark is very angry.
The people in Apartment (公寓) 2 are dancing. The man in Apartment 3 is cleaning the carpet. The woman in Apartment 4 is practicing the violin. The high school students in Apartment 5 are listening to rock music. The dog in Apartment 6 is barking loudly. And the people in Apartment 7 are having a big argument (争吵). Mark can't stand it. What can he do? And how can he spend such a long and sleepless night?
