My children wanted ball pythons years ago and before we would allow them to get one they had to go online and do research then they had to write a report on the care, health, husbandary, etc... of them. Then they had some interaction with them at a show and then we allowed them to each get one. They have been raised around burms (many many burms) but they had to show they were responsible enough to get their own snakes before we allowed them to get one. Just show your mom you are serious about getting one and prove you have taken the intiative to do some research on your own.
