OP, I've watched this thread and have seen people saying just get it, or give their experiences regarding it, and also watched people give other good advice. My personal advice is to not get it without her permission. If you show maturity at your age in going about it the right way, it will go a long way. Tricking your parents and hiding an animal in your closet is not a sign of responsibility and maturity. If you do extensive research, learn everything you can, take responsibility and maybe even ask your dad to help sway her. If he's okay with it, and you show your passion in a positive manner, with your dads approval she may agree. Last thing you want to do is risk your parents trust at such a young age. And ball pythons don't belong trapped in a dark closet for any amount of time either.
