Once a snake used to live in a zoo and had been friends with many of the animals, it used to go to different animal cages at night to visit them and talk with them. One day a lion was found dead in its cage, everyone was surprised what happened to the lion but then nobody noticed anything else. Couple of days passed and a hippo was found dead again.
The owner of the zoo was surprised what was happening and animals were dying all in sudden and none of them were ill or so. The very next day tiger and its cub was found dead too. Zoo owner set an investigation team to deal with the matter.
The team used to sit at night along the cages and one of them saw the snake crawling into the cage, the guard attacked it but it bite him in his foot so he died. The next day a wolf and a person were found dead. The investigation became intense, 10 guards at each cage and the very next night they found out about the snake doing it so they killed that snake. The next night none of the animals died. They found out the snake used to offer friendship and then eat them up.
Moral:
Never trust snakes 🐍 because they can never be your friends. They can harm you whenever they will find some benefit from you, they will bite you in your back or tarnish your esteem.
The nature of snakes never changes, so people who have a snake-like nature should stay away from such poisonous people.
