My new landlady was horrified when I told her I had snakes. She began hopping up and down and swatting at herself (seriously). She wanted them gone.
I calmly and patiently reasoned with her about the fact that I kept them in very secure cages, they would not destroy the apartment, they would make no noise, and I would tell no other soul in the building that I had them.
She relented and allowed me to keep them. However, I cannot even say the word "snake" or she will begin her dancing routine again.
