[Dingle-Dingle]

The traffic light on the corner buzzes when the lights turn red and it is safe to cross the road. I was crossing with an intellectually challenged friend of mine.
She asked if I knew what the buzzer was for. I explained that it signals blind people when the light is red.
Appalled, she responded, 'What on earth are blind people doing driving?!'
She is a Local County Council employee. (And she's NOT blonde).
