You live life alone when you're different.
She lives every second separate from the rest of everything. She repels; she's a magnet in reverse, and when she walks into a crowd, the crowd shifts away. Flinching's just like a gag reflex, she's realized, and you can learn to suppress it if that's what surviving takes. She's got to be tough because it hurts, that space they leave between them and her, that kind of empty.
But she's a survivor and she toughens like evolution meant. As long as she's rock through and through, she's safe.
