Braille

We're in the car and I'm driving. There are bumps on the center of my steering wheel to indicate where the horn button is located.

Me: "You know. Car manufacturers should make these bumps say something in braille. Like 'horn'."
('Reading' each line I softly say): "Horn. Horn. Horn. Horn"

Casey: ...(pause)...

Casey: "I think there's a very good reason why car manufacturer don't write anything in braille on the steering wheel of a car."

Me:

Me: "OOOOOOH!! "

Hysterical laughter erupts from both of us.
