The two children's books were created by D. Michael Pain in the 1970's. The Ugly Christmas Tree The Ugly Christmas Tree is about different types of trees. As people, we all can be different - yet the same and beautiful. You should treat people the way you want to be treated and not bullied for who you are. Rosco the Reluctant Rabbit Rosco the Reluctant Rabbit is about how you should never take things that are not yours and be grateful for what you have. Roscoe teaches us valuable lessons on compassion, confidence, and honesty.
