Content

The song is a moderate up-tempo, described as sounding similar to The Byrds. It features both members of the duo describing their later teen years — buying a pickup truck, sneaking into a bar, and even being imprisoned. After reflecting on their experiences, they then list the various lessons they've learned since their rebellious beginnings (such as how "A Sunday sermon can turn life around"), eventually stating that they were "learning so much more than / Back when [they] knew it all".
