And then I see my mother sitting by the open window, her dark silhouette against the night sky. She turns around in her chair, but I can’t see her face. “Fallen down,” she says simply. She doesn’t apologize. “It doesn’t matter,” I say, and I start to pick up the broken glass shards. “I knew it would happen.” “Then why you don’t stop it?” asks my mother. And it’s such a simple question.
