Technology Confusion

A lady came to the hospital to visit a friend. She had not been in a hospital in many years and felt ignorant about the new technologies. A technician followed her onto the elevator wheeling a large machine with tubes and wires and dials and lights that she thought might be a ventilator.

"Boy, I would sure hate to be hooked up to that thing," she said.

"So would I," replied the technician. "It's a floor cleaning machine."
