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 mistakes vanish, you lose a part of yourself. You get smaller and smaller every 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 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. ♥
