A report from Dear Webby

The passenger tapped the cab driver on the shoulder to ask
him something. The driver screamed, lost control of the car,
nearly hit a bus, went up on the sidewalk, and stopped
centimeters from a shop window.

For a second everything went quiet in the cab, then the
driver said, "Look mister, don't ever do that again. You
scared the daylights out of me!"

The passenger apologized and said he didn't realize that a
little tap could scare him so much.

The driver replied, "You're right. I'm sorry, it's not
really your fault. Today is my first day as a cab driver.
I've been driving a hearse for the last 25 years".
