The song "Mother-In-Law Blues" by Buddy Guy is about the struggles and frustrations of dealing with a difficult mother-in-law. The lyrics express the singer's love for their partner, but how their mother-in-law's behavior and interference in their relationship create tension and problems. In the song, the singer describes how their mother-in-law always wants to be involved in their activities, even going as far as wanting to join them on rides in the country. This leads the singer to trade their car for a sports car with bucket seats, just to have some privacy and escape from the mother-in-law's constant presence. The lyrics also mention the mother-in-law eavesdropping on phone calls by being on the extension line. This invasion of privacy adds to the singer's frustration and annoyance. The singer also finds it difficult to watch television in peace, as the mother-in-law often interrupts and changes the channel. The song highlights the traditional notion of a man's home being his castle and where he should be the king. However, the mother-in-law's presence in the house undermines this idea and creates a challenging environment for the couple's love to flourish. Overall, "Mother-In-Law Blues" portrays the struggle of trying to maintain a harmonious relationship despite the interference and challenges posed by a difficult mother-in-law.
