Pencil: I'm sorry....
Eraser: For what? You didn't do anything wrong.
Pencil: I'm sorry coz you get hurt bcoz 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. Eventhough 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.
p/s: if you can't be a pencil to write someone happiness,
try to be a rubber to erase their sorrows...
