Chuck Palahniuk. Lullaby (№ 308)

All of our thoughts are someone else's. Because it is impossible to concentrate. Just sit down and calmly think it won't work. Some noise will leak. The singers screamed. Dead laugh. Actors cried in a voice. All those emotions in small doses.
Someone always sprays in the air your mood.
Radio in the cars spill around someone's grief, someone's anger or joy.
