"The Snake" (1968) by Al Wilson tells of a tender-hearted woman who finds a dying, half-frozen snake on the side of the road. Taking the snake home, she revives it and hugs it. The snake later bites her, then says to her as she lies dying in disbelief, "Silly woman, you knew I was a snake before you brought me in!"
