This song is about the place where Luff ended up when it got tired of responsibility. He was lulled into his old comfort and safety zone and forgot about his journey for a while. Luff eventually found his way back, but the Smilers were relentless. They are those who would convince you that they know best and would sell you their own mother if it would profit them, but they would have a clause in the contract that they would get their mother back too. They have everything just right to fool you.
Sit back and relax and enjoy the Smilers.
