This song was released in 2013, and is the producer's 14th original work. The lyrics are commonly believed to be about child abuse, as the mother character continues to neglect and demean the child throughout the latter's life. The child grows up and eventually "disappears" (oft interpreted to be the result of suicide), causing the mother to enter a spiral of self loathing and guilt, blaming herself for her child's "disappearance" and calling herself a useless child.
