"Mom had grown up in the desert. She loved the dry, crackling heat, the way the sky at sunset looked like a sheet of fire, and the overwhelming emptiness and severity of all that open land that had once been a huge ocean bed. Most people had trouble surviving in the desert, but Mom thrived there. She knew how to get by on next to nothing. She showed us which plants were edible and which were toxic. She was able to find water when no one else could, and she knew how little of it you really needed. She taught us that you could wash yourself up pretty clean with just a cup of water. She said it was good for you to drink unpurified water, even ditch water, as long as animals were drinking from it. Chlorinated city water was for namby-pambies, she said. Water from the wild helped build up your antibodies. She also thought toothpaste was for namby-pambies. At bedtime we'd shake a little baking soda into the palm of one hand, mix in a dash of hydrogen peroxide, then use our fingers to clean our teeth with the fizzing paste."
