THE HOSPITAL'S emergency room smelled like soap. The place was nearly empty when I carried Mia inside, just one couple and their kids sitting in a circle in the corner. The parents  glanced up at us, then went back to praying quietly. The kids stared at the floor the whole time. I dropped Mia into a chair at the nurses' station and waited. Behind the glass wall in front of me, three nurses were talking about their various ex-husbands. It sounded like the same guy to me. I was still waiting for them to figure this out when one of them came over and asked, "What's the problem?" "No problem," I said. "I just want to drop her off." We both looked at Mia. A string of drool slowly slipped from her chin to her chest. "Has she been drinking?" the nurse asked. "I'm not really sure," I said. The nurse looked back at me. "You're not really sure? Now what does that mean?" "I don't know," I said. "I found her. I thought maybe I could leave her here." "Sure, we'll just have to fill out the paperwork for that," the nurse said. She smiled at the other nurses when she said it, and I couldn't tell if she was joking or not. She had me go through Mia's pockets, but all I could find was a piece of paper with an address written on it. Five Crossings. I couldn't find her ID anywhere. The nurse entered my name and address on a form, then took us down the hall to another room. What seemed like hours later, an old, red-faced doctor finally came in. He glanced at Mia and then washed his hands in the sink. "You the father or the boyfriend?" he asked. "Neither," I said. "I've only just met her." I couldn't take my eyes off the garbage can in the corner. It was full of bloody bandages. I wondered what had gone on in there before we'd arrived.
