how frank used to call hanretty every christmas showed how he craved for someoen to care for him. and how his face used to lighten up when he used to talk to his father and how he used to write him letters. it was clear that the upbringing he had played a great part in his character but it was also his choices. he did truly love his parents. it hurt him to see them get divorced and when he saw that his mother had built this whole new life. thr moment hanretty says you're free to go because no one is chasing you now. he realises there's no point in running. he had done and accomplished everything he could have with the money and the riches of life. he knew that meaning only comes by doing meaningful work and by being with people who care abt you and who you care about.
