I used to believe that my dog had video cameras implanted in her eyes and that every spot little on the wall or ceiling was also a camera or a secret hole through which my parents could spy on me. I'm not sure whether I actually believed this or whether it was merely my imagination at work, but I was alway cautious not to do anything "bad" in front of my dog.
