Andrew missed two mortgage payments and the bank called his father, whose name remained on the title. His parents confronted him and, seven years after he placed his first bet, he confessed that he had a gambling problem. It came as a complete surprise. His mother said it felt “like we were hit by a truck.” For his father, the confession immediately explained so much of Andrew’s behavior the previous few years: his shabby clothes and beat-up car that seemed out of place for a young attorney, his isolation, his use of the family credit card for innocuous purchases, his moodiness, his encyclopedic knowl- edge of seemingly every sport, his addiction to his phone, and so on.
