Pencil and eraser

pencil : you know, i'm really sorry.

eraser : for what ? you didn't do anything wrong.

pencil : i'm sorry, 'cause u get hurt because of me. whenever i make 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 actually happy with my job. so please, stop worrying. i hate seeing you sad :)
