I laid a wooden floor this afternoon and the lady had the TV running and the radio, we were talking and my machines were running too,her two dogs were barking and her two parrots squiecing and hustling and laughing and... She said she needs some life around her, some action all the time. She couldn't stand quietness. Her age: about 60. I nearly couldn't stand this hellish melting pot of noises. And she loved it.People are different(some are too different for me)
