When I was little I always believed that if you hid somewhere, even if it was behind something as thin as a pole, and you couldn't see anyone else then they couldn't see you either. I remember hiding behind something really thin and asking my friend if she could see me and of course she said yes. That pretty much caused me to believe otherwise.
