Pencil: I'm really sorry.

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

Pencil: I'm sorry 'cause 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. You get smaller and smaller every time.

Eraser: That's true but I don't really mind. You see, it's my job. 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.

I've always enjoy playing the role of an eraser but as I get older and older, I get smaller and smaller and would eventually vanish. Hopefully, nobody will miss me when I'm gone so that the new eraser can do its job. However, those who know me will know that I'm a pretty long eraser and  it would take quite some time to  erase me off, so to those who are hoping to get a new eraser soon, sorry to disappoint you.
