This song is a nostalgic anthem that explores the passage of time and the loss of innocence as we grow older. It's a look back at the carefree days of our youth, when we typically thought we were capable of anything and that our friendships were so strong they would endure even in death. The title explains this well enough, because when we're older, we often find ourselves reflecting on our old days, "when we were kids."
