Driving

Two elderly women share the driving back and forth to church on Sundays. This particular Sunday they were out driving in their large car -- both could barely see over the dashboard.
As they were cruising along they came to an intersection. The stoplight was red but they just went right on through.
Ethel, 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 intersection. The light was red and again they went right through, narrowly missing a turning vehicle.
This time Ethel was almost sure that the light had been red but was still concerned that she might be mistaken. She was getting nervous and decided to pay very close attention to the road and the next intersection to see what was going on.
At the next intersection, sure enough, the light was definitely red and they went right through almost hitting a pedestrian.
Ethel turned to the other woman and said, "Mildred! Did you know you just ran through three red lights in a row! You could have killed us!"
Mildred turned to her and said, "Oh, am I driving?"
