George Pharmacy is a pharmaceutical sales rep who has been very successful at his job in the last few years. Unfortunately, his family life has not been very happy. Three years ago, his only child, Anna, was out for a drive when she was hit by a drunk driver. She and her husband were killed and their $14-$year$-$old son, Kevin, was blinded in the accident. He also suffered extensive injuries to his jaw that have required major and prolonged dental work.
