Pencil and Eraser

Pencil : You know, I'm really sorry 

Eraser : For what? You didn't do anything wrong.

Pencil : I'm sorry, because you get hurt because of me. Whenever I make a mistake, you're always there to erase it. But as you make my mistake vanish, you lose a part of yourself. You get smaller and smaller everytime.

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 of these days, I know I'll be gone and you have to replace me with a new one, I'm actually happy with my job. So please, stop worrying. I hate seeing you sad :)
