Old Python Myth

[BOASandBASS]

I have heard this old myth/story many times and i am curious as to were it comes from.

A man bought a baby python when he saw an old man selling them at the market so he quickly bought one and took it home. Over the next many years he and his "companion" got very comfortable with each other, that they would sleep in the same bed together, were the snake would curl up against him and warm up. Then one day he noticed that his python was not resting in a curled or coiled position anymore, but it was lying down next to him fully extended. Because of this the man took his pet snake to the doctor to receive an explanation. The doctor told him his snake was sizing the owner up to eat him. Upon hearing this the man killed his python to avoid accident.

Has any one heard this before? When i was trying to convince my mom for a snake she told me this story as a deterrent. BTW she is turkish and i have heard this myth from another middle eastern person. Does anyone have any info on this? Im just curious.
