There was a story posted on what I think was one the previous GuroChan domains.

The story was about a mother that "recycled" the life of her delinquent daughter, taking her daughter to some timeline-altering recycling center to regain and recycle the time spent on raising her daughter, instead gaining things like new skills and such that the mother would have had if she never had said daughter (I think I recall the mother gaining fluency in other languages as well as the ability to play the piano).

The story ends with some reality/timeline alteration so that the daughter really actually never was born and the mother not even remembering her.
