This included throwing a glass of cold water in the boy's face when he was having a particularly heated argument with his mother at the dinner table. 'He was nasty,' says Libby Armintrout, Bill's younger sister. 'I'm at war with my parents over who is in control,' Bill Gates recalls telling a therapist, who told his parents that their son would ultimately win the battle for independence, and their best course of action was to ease up on him. The rest, as they say, is history. The accompanying Gates Family Album is also worth a look."
