Pencil: Im sorry
Eraser: For what?
Pencil: I'm sorry because you get hurt because 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! :(
Eraser: That's true, but i dont 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 & you'll replace me w/ a new one! :)
