What was "The Play That Changed Your Life"? Not only the title of a new American Theatre Wing book, which posed that question to 19 of America's most distinguished playwrights, but the start of a discussion by two of those playwrights, Tina Howe and Diana Son. They also talk about which of their own plays changed their lives; what role theatre played while growing up; if there were teachers who inspired them to get involved in theatre writing; what drew them to playwriting; how much of themselves are in their characters; and their role as mentors for young writers.
