Listen, years ago, one of my salesmen had a couple he sold tires to. The man was blind but did all the talking for the sale. When the tires were all mounted up, the keys were given to his wife. They left the building but, he came back in angry a few minutes later. He took his salesman, Steve, out there, squared off against the driver's side of the car and, angrily pointed to the front wheel demanding Steve answer, "Does this look right to you?". Steve got all flustered and apologized as he told the man that he couldn't see anything wrong. The man instantly perked up and smiled saying, "Neither can I, I'm totally blind."
