At 3 or 4 years old, I believed that the walls of your house were hollow and served as massive water reservoirs. The taps literally opened a hole in the wall and let all the water just fall out. This strange belief system also held that if you forgot to turn the tap off, your house would flood, with the whole street following soon after, finally resulting in a Biblical Deluge which would basically destroy the world. A panicky "forgot which way to turn the tap off" incident, combined with a number of nightmares about small leaks in the walls of our home, saw me become the "Guardian of the Taps" at my kindergarten. When time came to wash up before our snack, I would man the sink and ensure the safety of our planet.
