A snake wanted to love him or eat him!?

My brother's friend had an unusual family pet.  One of his pets was a snake.

One morning, he work up and he saw his pet stretched out dead straight beside him.  It had uncoiled itself and was sleeping like a person. 

A snake usually coils itself up to sleep, but it had not done this.  He only asked help from a reptile expert.  He was told that the snake was measuring him up.  If it had been long enough, he could have been eaten. 

He might have thought his snake was in love with him, if it had become a human.  However, the fact might be the snake measured many times before when he was sleeping.

Finally, he got rid of his lover.
