Relationship counselor John Gray focuses on the differences between men and women--men are from Mars, and women are from Venus, after all--and offers a simple solution: couples must acknowledge and accept these differences before they can develop happier relationships. In this unabridged version, Gray gives a spirited delivery of his message, especially when role-playing typical male/female interactions. Although it takes some time to adjust to his slightly nasal tone, the information is sound and gives both men and women helpful hints on improving themselves and their union.
