A Swan and Goose were raised together; one for song and one for supper. The cook picked the Swan but he sung out and saved his life. A man cannot be too careful of what he does, where the life of any creature is in question.
A Raven desired a Swan’s white feathers. He thought the color was due to the water so he went to live in the lake. Not water, and going hungry, he perished. Change of habit cannot alter nature.
