Pencil: I'm sorry....
Eraser: For what? You didn't do anything wrong.
Pencil: I'm sorry bcos you get hurt bcos of me. Whenever I made a mistake, you're always there to erase it. But as you make my mistakes vanish, you lose a part of yourself. You get smaller and smaller each time.
Eraser: That's true. But I don't really mind. You see, I was made to do this. I was made to help you whenever you do something wrong. Even though one day, I know I'll be gone and you'll replace me with a new one, I'm actually happy with my job. So please, stop worrying. I hate seeing you sad. :)
I found this conversation between the pencil and the eraser very inspirational. Sister is like the eraser whereas their brother is the pencil. They're always there for their brother, cleaning up their mistakes. Sometimes along the way... they get hurt, and become smaller (older, and eventually pass on). Though their brother will eventually find someone new (spouse), but sister are still happy with what they do for their brother, and will always hate seeing their precious ones worrying, or sad.
