There were 15 people in my house when the well ran dry. It was Thanksgiving, and everyone knew that they did not have to flush every time. Those who were spending the night had learned how to take navy showers: turn the water on long enough to get wet, turn it off, soap yourself, turn the water on long enough to rinse, and turn it off again. If the water ever gets really nice and hot, then you know that you have left it on too long.
Everyone knew this, but we still ran out of water. When I turned the kitchen tap to fill the coffee pot after Thanksgiving dinner, all that came out was a long airy gasp. “We’re out of water!” I yelled. People looked at me uncomprehendingly. Surely that one little secret flush had not made the difference. Surely that one extra minute under the showerhead had not caused everyone to go without water for the rest of the afternoon. But it had.
