Famous story about Rabbi/ Dr. Twerski, copied from Ohr Somaych Web site:
I once heard Rabbi Dr. Abraham Twerski, shlita, tell a beautiful story about a rebuke that he once received from his saintly father, the Hornesteipel Rebbe, zt”l. He told this story at the 10th anniversary of the passing. He told it as an example of rebuke that makes its point and expresses love at the same time. The story took place on Rosh Hashanah when Rabbi Twerski was a young boy. Staying at their house was a man who should have known better, but asked the young Abraham Twerski if he would play Chess with him. The boy felt that there must be something wrong with playing Chess on Rosh Hashanah, but the man assured him that there wasn’t – “What could be wrong with a game of Chess?” So, they played and the young boy Checkmated the older guest. Later that night after Rosh Hashanah ended, young Abraham Twerski was told that his father wanted a word with him in the study. Nervously, he entered. His father, never taking his eyes from the book that he was studying, chided the boy “You played chess on Rosh Hashanah?” The tone said that he knew him to be above this kind of behavior, and that he was disappointed with him. The rebuke struck deep in the little boy, who felt very ashamed. When the father was certain that he had made his point, he lifted his head from the book he was studying, picked up his glasses and with a twinkle in his eyes he said to his son, “Did you win?”
