'Carolyn' --Merle Haggard (1972)

Wandering Words: "I believe a man will do that sometimes out of spite, but, Carolyn, a man will do that always when he's treated bad at home."

Haggard broaches the subject of infidelity to his wife by saying he's "heard about a man" who sees other women to make him feel "warm." Perhaps it's a secondhand story; more likely, he's gauging her reaction before telling her the full truth.
