True story - John, a magazine writer, makes his first trip to visit Mastow, a complete stranger who is living in a retirement home. John has only a room number and a name, both written on the back of a Chinese food menu beside a single, circled word: 'Mushrooms.' What starts as a bizarre transaction becomes an important moment of connection. This is a story about being afraid to get old and learning how to age with grace. It's about the ways in which losing people affects us. It's about talking with people who are much older or younger than you are. It's also a little bit about hallucinogens.
