When I first read the "sticks and stones" phrase I went through some english class induced revulsion at the cliche, but then you used it very nicely! That was my favorite part, in fact - how you used that as a way of tying the story together and building to when she used it as a suicide note. If you were to expand it, however, I think it would be nice if the sister had an epiphany when she saw that the protagonist is dead. But then again, that sort of thing is rather cliched. *revulsion*
