Later that morning, a teenage girl was walking aimlessly down the street. Her hair was messed up, she was wearing a gym uniform, and she had dried sweat stains on her shirt.
"Are you all right?" a passerby asked her.
"No one else asked," she said in a daze. "I...no one noticed me. I must be no one."
"What?"
"I thought I was someone named Sarah...but she's still at school. I don't know who I am..."
"Let's get you cleaned up and we'll call the police to help you." The girl needed a shower and some clean clothes.
