Why do some people return their ball pythons?

[hihit]

and let me tell you, be prepared for mistakes when you get your ball python, sometimes things work good but then you get the snake and something breaks or doesn't work and you need a new one.

I definitely expect to make some beginner mistakes lol, just like with any new thing. But I hope with the amount of research I've been doing that those mistakes won't be too severe and that I'll be able to correct them when they happen.
