(CNN)When Missouri art teacher Misty Byrd learned that the mother of one of her students needed a new kidney, she said she didn't even think about it -- she picked up the phone and offered hers. After a successful transplant and developing a close friendship, both women are now working to find a kidney for a local father who is waiting on the transplant list.
