We hear Billie Holliday, Keely Smith and Leo Reisman (with Anita Boyer) asking the musical question, "What Is This Thing Called Love?" And, reporter Sean Cole talks about love with Joe and Helen Garland, who fell in love during World War II, but married other people. Thirty years later they met again, felt the same love they felt when they were young, divorced their respective spouses, and finally married each other.

Host Ira Glass talks with This American Life producer Julie Snyder about a personal regime change that happened when she was a kid, after her parents got divorced and her stepdad came on the scene. She says that by the time her parents separated, literature on what to tell the children was everywhere, and the kids took it relatively well.
