I was thinking today of an old friend, "D", who moved away several years ago. Lousy correspondent that I am, I've lost touch with her, but we shared a lot of laughs in our time together. "D" was a super-bright woman, extremely intelligent under normal circumstances, but she did admit to an occasional mental lapse. Since I don't know where she is, and she doesn't know I'm here, I'll share this story at her expense:
One evening "D" and her husband were relaxing outside, enjoying a cool drink, when he suddenly stood up and walked to her car. He leaned down, rubbed his hand across the top side of one of her brand new tires, and pointed out a bad scrape.
He: "What happened to your new tire?"
She: "I have no idea. I've never seen that before."
He: "Did you run over something in the last day or two?"
She: "Noooo...well, I rubbed against the curb, but that would have been on the bottom."
