Doing this can DRASTICALLY affect people's behavior....

The ancient art of Feng Shui is based on the fact that environment does indeed affect not only the seen world but the unseen as well.

I know I have immediate mood changes from sounds alone.
The big bass vibrating from the kid's car makes me irritable and the birds outside of my window always make me happy.
The phone ringing in the afternoon makes me wonder but if it rings at midnight mad.
The church bells ringing on Sunday morning make me feel guilty for staying home and sleeping in.
