THE CREEPY SNAKE STORY [TRUE!]

My teacher told the whole class a story about her friend's daughter...

My teacher's friend had a house full of 'pet snakes' and they are all tamed so they wouldn't harm visitors.
One day, there was this pet snake who wasn't eating anything and it kept on shredding it's skin after it had already shredded it's skin already. When the snakes are sleeping, the snake was sleeping in a strait line instead of curling up. The daughter of my teacher's friend thought there was something wrong with the snake so she took that pet snake to the vet.
When she took it to the vet, she told them that the snake was acting very strange. It kept on not eating for so long and it kept on shredding it's skin even though it had already shredded it's skin. The vet said that it's natural for snakes to do that. The daughter said that the snake was also sleeping in a strait line instead of curling up. This time, the vet had a weird expression and said that the snake is actually preparing to eat the daughter! The vet had to get this injection thing and then they had to use it on the pet snake.
