Understanding neighbor Bashny.Net

Until the summer, occasionally working from home. A neighbor from the top to make repairs, and that is very hard drills out of the walls (well, as is usually the case).

I need to call the customer understand that if he is drilling - will not hear anything. I yell "Man, do not drill, I'll call the" (prefabricated house, you can talk in a whisper). A neighbor knocked twice on the battery, saying "message received" I talked, and shouted, "All you can drill," after which he safely continued.
These are the neighbors are.
