eraser and pencil

PENCIL : you know 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 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 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 actally happy with my job. So please, stop worrying , i hate seeing you sad :'(
