Once upon a time, there was a unicorn and a bear. The unicorn's name was mary. Mary was white and she had pink hair, and she had gold hoofs and wherever she went she left a trail of rainbow glitter! The bear's name was bob. Bob was very grumpy. Wherever he went he had a frown, and left a trail of raindrops. He was big and brown. Mary and bob were not friends. Bob was not nice to mary, and her cheery sparkles made him even grumpier. One day bob got a fever. Nobody in the entire forest would come close to him or help him because he had been so mean and grumpy to them. But mary took care of him. Mary's kindness rubbed off on bob and he started to be nice and they lived happily ever after as best friends. 
Always be nice to others; being mean won't get you anywhere.
