Okay, I was thinking about how Wicked the musical and the Wizard of Oz have a common theme of friendship, and this sort of came out. Each line is written with a character from the Wizard of Oz or Wicked in mind but many could apply for multiple characters and it's also supposed to be sort of universal so I'm not saying which is which.

To the friends that matter

Living or Dead

Inside of Oz or out

No matter what you've done to hurt me

Or I've done to hurt you

Whatever secrets may be between us

Thank you for being my heart

My courage

My brain

And for changing me for good
