I had the same problem when I was living with my aunt. She would not allow reptiles of any kind. We had one house cat and that was it. I finally talked her into letting me have a small conure. I hid a tarantula under my bed and she found it... that did not go over well!

In the end, I had to wait until I moved out to go to college until I could get my first snake. I also had mice, tarantulas, and a bearded dragon. Now I have a nice number of snakes, a crested gecko, rats, 2 dogs, one cat...

Anyway the point is, if you can't do anything about it, leave it alone... it's a waste of good energy to be angry about it. At the same time I know how it feels to want something and have someone hold you back from your passion.
