Snake in the Forest

I had a friend tell me this piece of folklore, “A woman finds an injured rattle snake in the forest. She brings it back home and nurtures it back to health over the course of a few weeks. Finally, as she is getting ready to release it back into the forest, it bites her. ‘Why did you do that? I saved you!’ she shouts at the snake. ‘look, bitch’ the snake replies, ‘you knew I was a snake.'” He told me that this was a Native American folktale. It seems to indicate that a snake is a snake and even if you nurture and care for it, it will still act like a snake. The nature of the creature cannot be changed.
