Robert and Anthony (real people, real names) played a lot of golf together for many years. Evenly matched in strengths and weaknesses of their games, nothing pleased them more than getting into the other’s wallet, regardless of the numbers on the scorecard.
Then, Anthony went on a streak — not just winning, but winning by increasingly wider margins. Finally, Robert could take it no more, asking Anthony what he had done. Had he been sneaking lessons? Reading books? Changed his diet? Started working out? Anthony wouldn’t budge; he just kept on winning.
