When I was young (about 3-4 years old) I believed that owls lived in keyholes. Therefore, I would not go too close to a keyhole, unless there was a key in it, which would prevent the owls from coming out and attacking me. Fortunately, after a while my parents bought me a somewhat lifesize toy owl, which made me realize that owls were too big to live in keyholes.
