For some reason I think of the first time I saw her, kicking the shit out of the vending machine that refused to release her candy. Before that day, every hour of my life had been exactly like the one before it. Relentlessly boring. Painfully monotonous. But then she walked out of my waking nightmare and into my life, a complete mystery from Second One. Her presence was a problem I needed to solve, a problem that finally interested me. And then, somehow, she made me interested in myself. Mara began as a question I needed to answer, but the longer I'd known her, the less I felt I actually knew. She was constantly surprising, infinitely complex. Unknowable. Unpredictable. I have never met anyone more fascinating in my life, and all the time in the world wouldn't be enough to ever know her.
