Octogenarian ladies Maggie and Maud, a couple of lifelong friends, were driving through town one day.

Both had shrunk in size a lititle, as aging ladies do. Bless 'em.

Maggie could barely see over the steering wheel of her ancient Morris 1000.

She ran a red light and Maud cringed, yet said nothing.

Then at another set of lights, Maggie drove straight through on red but Maud just wasn't too sure what she had just witnessed.

Finally, at the third set of lights, Maggie drove straight through on red again.

Maud, buttocks now firmly clenched, said "Maggie, please don't be upset. I'm not criticising you but I think you just drove through three sets of red lights in a row."

"Good heavens." Replied Maggie. "You mean I'm driving?"
