Pencil: I'm sorry.
Eraser: For what? You didn't do... anything wrong.
Pencil: I'm sorry, 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 and 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. I'm actually happy with my job. So please, stop worrying I hate seeing you sad.
"Sometimes we have to be like the eraser, whereas someone we love is the pencil. We're always there for them, cleaning up their mistakes. Sometimes along the way we will get hurt and become smaller (older and eventually pass on). We are made to to this. Sacrificing self needs and wants and fulfilling the one we love... "
