I feel like it's about hurting someone you were once close to. When you hurt someone, it leaves a stain. It's not something you can just scrub away. And no matter what happens in life, it's still there. And even though the singer was depressed about it once, he has let himself begin to breathe and leave it all behind and forgive himself, but he acknowledges that the stain remains for the other person. We never get over what we do to other people and what they do to us. The stain is always there and we just need to learn to put a piece of furniture over it, or ignore it, or embrace it.
