“Life is unpredictable,” I said, “and we are not always the people we think we are. If we’re unlucky, that’s when we discover it. When something like that happens, you have two choices.” Or, more than two, but distilled, they came down to two. “You can admit the error and resolve never to repeat it, or you can refuse to admit error and throw every effort behind insisting you were right to do what you did, and would gladly do it again.”
