chunk: The morning after the party, Andrew proceeds to the appointment. In the waiting room, he meets a young woman named Sam (Portman), who is a pathological liar. She later explains that most times she does not know why she lies and will always admit to them afterward. In Andrew's meeting with his doctor (Ron Leibman), it is revealed that Andrew has been on lithium and other mood stabilizers, as well as antidepressants, for his entire adult life, but has recently stopped taking them. He also says that his father, who is his psychiatrist, put him on the medication. Andrew finds Sam outside the office and offers her a ride home. Sam invites him into her house, and he meets her mother, who inadvertently reveals that Sam has epilepsy. Andrew tells Sam of his mother's death, and Sam tearfully eulogizes her hamster. After returning home, Andrew's father confronts him and is insistent that they have a talk before Andrew leaves.
