As others have said, this song is about John Rzeznik's experiences growing up as an orphan. The song is apparently spoken from his view, and talking to one of his four older sisters, because they're the only ones who are going through the same experience ("If you could hide beside me, maybe for a while, and I won't tell no one your name"). The lines "Scars are souvenirs you never lose / The past is never far" show that, although his parents' deaths were long ago, he'll live with the pain forever. "Reruns all become our history" is the memory that his family has of the loss, and "I think about you all the time, I don't need the same / It's lonely where you are, come back down / And I won't tell your name" is him speaking to his parents.
