While I think Emo pretty well nailed the meaning of the song, I'll add a note about the interesting switch in gender perspectives this song does. In the first verse, we get the typically female relationship concerns ("it's a dilemma of girls and boys for centuries should I be with you? should I forget about me?). In the second verse, we switch to typically male anxieties (“it's a dilemma of boys and girls for centuries do I really know you? do you really need me?”). I think some people may assume that this song is sung from the perspective of one person, when in fact the story is told by both members of the relationship.
