My father wakes me at eleven o'clock. It is late and I am tired. "Come," he says. "Bring your coat." We go to the roof. It is cold. The sky is very clear. "Look at the moon," he says. The moon is big and red. It is not white tonight. "Why is it red?" I ask. "The earth is between the sun and the moon," he says. "We are the shadow." I look for a long time. The moon changes very slowly. At midnight we go down. I am cold and happy. "When is the next one?" I ask. "In three years," he says.
