A friend always seemed to lean slightly to the left. It bothered me, so I suggested that he see a doctor and have his legs checked out. For years, he refused, telling me I was crazy, but last week, he finally went.
Sure enough, the doctor discovered his left leg was a centimetre shorter than his right. A bit of orthopaedic surgery later, both legs are exactly the same length and he no longer leans.
“So,” I said, “you didn’t believe me when I told you a doctor could fix your leg.”
“You were right,” he said. “I stand corrected.”
