A passenger in a taxi tapped the driver on the shoulder to
ask him
something. The driver screamed, lost control of the
cab,nearly hit a bus, drove up over the curb and stopped
just inches from a large plate glass window. For a few
moments everything was silent in the cab,then
the driver said, "Please, don't ever do that
again.You scared the daylights out of me." The
passenger, who was also frightened, apologized and said he
didn't realize that a tap on the shoulder could frighten
him so much. To which the driver replied, "I'm
sorry, it's really not your fault at all. Today is my
first day driving a cab. I have been driving a hearse for
the last 25 years."
