I found another way in which Keith and I are opposites.
It happened on Saturday; we were running errands, so we went into several stores in a short time period. At the first store, I paid with my credit card. At the second store, he paid with his plastic.
I couldn't help but notice how quickly he swiped his card through the card reader. "Wow," I exclaimed intelligently. "You're a fast swiper! Aren't you afraid the card reader isn't going to recognize your card?"
Keith stared at me. "No," he said. "But I did notice that you swipe very slowly." Which is true; I want to give the machine plenty of time to collect all of the information it needs.
So there you have it--just another example of how opposites really do attract.
