Joe Quirk is turning 55 on June 5! Everything is mismatched just like where you lived in college! Perhaps when she says I bet you think this song is about you, she is meaning that several men could easily think it was about them and be wrong, but proving how vain they all are, as a group.
Especially now— they bring a sense of normalcy into the day and the coffee and espresso are two things I look forward to.
The person Simon is singing about in this song remains a mystery, as she has never made it clear who she wrote it about; rumors include Warren Beatty, Kris Kristofferson, Cat Stevens, and Mick Jagger, all of whom she had affairs with.
