In the middle of all that noise stood a girl named Emma.
She was holding several textbooks against her chest, wearing an old brown shirt and a pair of worn denim shorts. Her hair fell naturally around her shoulders, and when she noticed the camera, she gave a small smile.
It was the kind of smile people remember.
For years afterward, anyone looking at that photograph would probably assume Emma had been happy.
She looked confident.
She looked surrounded by people.
She looked like the kind of teenager who had nothing to worry about.
