One day young Dominic asked his teacher, St. John Bosco, to teach him how to be a saint. He eagerly listened to everything Don Bosco told him and put it into practice. He wanted Jesus and Mary to be his best friends and would rather die than commit a mortal sin. Several of the boys at the school admired Dominic and thought of him as a friend. He grew quickly in virtue because he was docile and obedient to all that Don Bosco taught him.
