- "You want to know what I think about the most? Let me set the scene for you. It's the night Dad finally snapped. And I'm sitting in the police station, freezing cold, because I'm in my pajamas. When the police came and picked me up from home. I was asleep. Remember? In bed. Alone. And the nice officer, he drapes the coat over my shoulders. I feel a little better. So I'm sitting there, and my cold little feet are dangling in air, and I'm waiting. I'm waiting for my mom to pick me up. 'Cause they said that they called you. Yeah. Yeah, they said it was just gonna be an "hour" and then they'd explain "everything". And then it was two hours. And the it was the next morning... When I lie in bed at night, staring up at the ceiling, unable to sleep, I'm not wondering my dad, finally, suddenly, snapped. No, that doesn't haunt me. What haunts me is you. You, who left me, when I needed you the most. With no explanation, no goodbye."
