I'm a teenager, I never really talked to others a lot and lately I've been thinking of getting a pet- a pet snake. Yeah my parents are against it but if I could know a way to get one, I'd be more than happy.

I really know nothing about pet snakes. What they eat? How they act? Where to get them? It's a new thing for me. That's why I'm kind of seeking help. 

Where do/can I get one? 
What kind is the easiest to look after?
If so what do they eat?
How should I talk to the person if I'd have to go in a shop?

I'm willing to do things just for a friend. Thanks a lot beforehand!!

.. also I'm new to reddit so I'm sorry if I made a mistake.
