The lyrics paint a vivid picture of a time when everything was simpler, when two people shared a deep connection and found joy in each other's presence.The line, "Cause we were happy," holds a significant meaning within the song. It encapsulates the central theme of longing for a past happiness, emphasizing that there was a time when the couple in question experienced genuine joy and contentment. The line acts as a bittersweet reminder of what once was, highlighting the stark contrast between their previous happiness and their current emotional state.However, this line also develops unexpected and imaginative themes that add depth to the song. One theme that emerges is the fleeting nature of happiness. It highlights how happiness can be easily taken for granted in the present, only to be cherished and yearned for in the future. The line suggests that happiness is not a permanent state, but rather a transient feeling that can dissipate over time. It encourages listeners to appreciate and hold on to happiness while they have it.Additionally, the line hints at the concept of misplaced happiness. It suggests that the couple's happiness may have been tied to certain external circumstances or experiences, such as walking along illuminated streets or dreaming about owning a farm.

It introduces the idea that the couple's happiness may be perceived through rose-tinted glasses, as memories tend to be romanticized and edited over time. This theme highlights the human tendency to remember the positive aspects of a past relationship while conveniently disregarding the challenges and conflicts that may have contributed to its end.Ultimately, the theme of longing for past happiness remains at the forefront of the song. While the line "Cause we were happy" serves as a reminder of what was lost, it also evokes a sense of hope and the possibility of finding happiness once again. In its simplicity, the line captures the essence of the song's emotional journey, leaving listeners reflecting on their own experiences of love, loss, and the pursuit of happiness.
