Yesterday, I'm driving home, and the mobile rings. Being responsible, I pulled over to the side of the road before attempting to answer it, by which time the phone had stopped ringing.
And while I'm busy with the phone, the passenger door opens, and I look up to see a little old lady clambering into the car.
Fortunately, my life experiences to date have equipped me with the perfect skill for dealing with this particular circumstance. I pasted on a smile and, feeling very Arthur Dent, managed to greet her with, "Er…hello?"
"You're early," she replied cheerfully. "And you're driving a different car."
"Ah. In fact, ma'am, I think I'm not the person you're waiting for," I suggested.
She peered at me, blinked, and said, "Oh! Oh, no, you're not!"
After which she promptly started clambering (in the slow and hesitant mannerism of the old and frail) out of the car.
