Two elderly women were out for a Sunday drive in a large car and neither could see over the dashboard properly. As they were driving along, they came to a junction.
The traffic light was red but they just drove straight through. The woman in the passenger seat thought to herself "I must be losing it, I could have sworn we just went through a red light".
After a few more minutes they came to another junction and the light was red again, and again they went right through.
This time the woman in the passenger seat was almost sure that the light had
been red but was really concerned that she was losing it. She was very
nervous now and decided to pay very close attention to the road and the next junction to see what was going on.
At the next junction, sure enough, the light was definitely red and they went right through, and she turned to the other woman and said, "Mildred! Did you know we just ran through three red lights in a row? You could have killed us!"
Mildred turned to her and said "Oh! Am I driving?"
