I agree with the others: your friends simply do not understand ball pythons. They are probably used to seeing snakes in aquariums and not in a rack. My family still has issues with my snakes being in a rack system. My mother still comes in and wants to "see" my ball pythons. I still have to explain to her that they are usually hiding anyway, so if she wants to see one, she has to take it out. For her pleasure, I do have one corn snake in a tank. She's not for breeding and is just a pet anyway (so I say this now...). However, she still doesn't like the fact that the corn snake is always hiding too xD
