It is not surprising that Biff's penchant for stealing continued throughout his adult life because Willy encouraged Biff's "little thefts" while he was growing up. As a result, Biff grew up believing that he was not bound by social rules or expectations because Willy did not have to abide by them, nor did Willy expect Biff to. He believed his father's stories and accepted his father's philosophy that a person will be successful, provided that he is "well-liked." Biff never questioned Willy, even when it was obvious that Willy was breaking the rules. Prior to his Boston trip, Biff adored Willy.
