"A mother brought her young son to Mahatma Gandhi. She begged, 'Please, Mahatma. Tell my son to stop eating sugar.'
Gandhi paused, then said, 'Bring your son back in two weeks.' Puzzled the woman thanked him and said that she would do as he asked.
Two weeks later, she returned with her son. Gandhi looked the youngster in the eye and said, 'Stop eating sugar.'
Grateful but bewildered, the woman asked, 'Why did you tell him to come back in two weeks? You could have told him the same thing then.'
Gandhi replied, 'Two weeks ago, I was eating sugar.'"
