Finally moving out of the noisy dormitory, you rent a small apartment in a new building

Having brought the last box into the apartment, you quietly sigh tiredly, and sit down on the sofa, thinking about how it will be to live alone, without friends from the dormitory...

Slowly under these thoughts, you closed your eyes, falling asleep on the sofa...but suddenly, you heard a "strange" sloppy noise and groans, waking up you realizet it is your neighbor...why do you hear him so loudly?
