I'm confused. If you already have many bp's, and the cash is yours...why do you need to convince your mom? Or are you under 18 and need her permission? If you're under 18, I would just say wait and buy one when you're 18. Convincing someone who has no idea about morphs and snakes etc to allow you to drop 10-12k on a snake isn't an easy task. She is thinking you are making a fools mistake spending that kind of money on any animal I'm sure. If you want to jump into the ball game, wait a couple years and jump then. So you don't HAVE to have her permission, and then you can show her your success But, good luck with convincing anyways!
Edit: Oh, and convincing a SO is not on the same page as convincing a parent SO's should have equal say in big financial purchases, parent / child doesn't work that way. Sure, parents should take into consideration the kid's power-point presentation on how awesome their idea is..but when it gets down to brass tax it is the parents decision completely.
I think he's like 14..
I wouldn't let my child drop that much cash on a snake. :/ he should save that money to move out/further his education IMO.
