A lot of people fail to see their special qualities, but they're there.
"The person's the rice ball and the plum is stuck to their back. So all over the world you could have rice balls made with all sorts of wonderful ingredients, all different flavors and shapes and colors, but since it's stuck in the middle of everyone's back, someone could have a plum and not even know it. They'd look at themselves and think "I'm so plain, nothing but white rice." even though it isn't true, because turn them around and sure enough, there it is...there's the plum. So if someone is jealous of somebody else's then it's probably because it's easier to see the plum on someone else's back than your own."
