Okay so the story goes:

Me: Post C/L ad for sand boa
Some guy: Emails me
Me: Call some guy
Some guy: Says "Hi how big do they get?"
Me: He's a male so about..... 2.5ft.
Some guy: Wells that's good. Will he get along with a ball python?
Me: Probably will mind their own business. But you CANNOT house them together.
Some guy: Why?
Me: They will both get stressed and maybe the ball will resort to eat him.
Some guy: SWEET! *whispers to girlfriend* THE BALL WILL EAT HIM!

Me: Have you even done any research?
Some guy: uhhhhh..... Kinda. How much is he again?
Me: Sorry but I have the right to say I will not sell him to you.*hang up*

SO the moral of the story is he was gonna house them together to see the ball python eat him, because he though it would be "SWEET". SO do not just sell your animals to anybody. Ask as many questions as you feel necessary.
