My wife and I had to sign some papers in attorney's office. Because we could not find a babysitter, we took along our four-month old son. Unfortunately, it took longer to transact our business than we planned, and eventually the baby was screaming at the top of his lungs. "Maybe we should close the door, " my wife suggested, 'so this noise won't bother your colleagues. " "Don't you worry," our lawyer said, "they will just think another client has received our bill."
