Figure of Eight by Paul McCartney delves into the complexities and cyclical nature of relationships. The song uses the metaphor of a figure eight to illustrate how issues in relationships often come full circle, repeating in a never-ending loop. Key themes include love, frustration, and the search for resolution. A particularly poignant moment in the song is when McCartney questions whether it’s worth persisting in a situation that seems to be going nowhere, highlighting the emotional turmoil and the desire for clarity.
