"We were sledding. Jamie hit me—" I say. “What?” Finny says. He doesn't shout it. He doesn’t need to. His narrowed eyes are enough to make me stumble over my words, “..with his head when we hit a bump and fell out." "Are you okay?" Mom asks. "I'm fine," I say. "But how do you know for sure?" she says. Finny suddenly pushes his way closer to me. "Are you dizzy?" he asks. "Blurred vision? Seeing spots." I shake my head to all. "Can you follow my finger?" He drags his index finger back and forth in front of my face. I tear my eyes from his to obey his request. He nods. "Okay," he says, "and you're not confused? You know who everybody is?"
