Unwanted advice

There is nobody so chesty as a normally unchesty man who suddenly becomes chesty, and I am sorry to say that the chestiness which had come to Ferdinand was the aggressive type of chestiness which breeds enemies. He had developed a habit of holding the game up in order to give his opponent advice. The Whip-Cracker had not forgiven, and never would forgive, his well-meant but galling criticism of his back-swing. The Scooper, who had always scooped since the day when, at the age of sixty-four, he subscribed to the Correspondence Course which was to teach him golf in twelve lessons by mail, resented being told by a snip of a boy that the mashie-stroke should be a smooth, unhurried swing.
