There is that story when a pet python cuddles up to its owner and refuses to eat. The owner after much failed effort to feed it, takes that snake to a vet. The vet after careful examination and questions offers this diagnosis to the owner – the snake was not cuddling, the snake was sizing the owner up to see how long it will take the snake to digest him. That’s why he did not eat. The owner was like a buffet meal!
Many so called friends hang around you, engage with you, only to exploit you and your abilities. One has to be very careful about people like one in the story. They do exist. And their only aim is to build their life by sucking out yours!
