" He wasn't staring into the fire anymore. He wasn't even here anymore. Behind those eyes, there was nothing but a dark place, far away and lightless, that he'd disappeared into.

I knew that look.

I knew that place.

...

Wherever he went , whatever dark place inside his head he crawled into, it wasn't a place for laughter, for words. It wasn't a place I could follow.

Places like that, everyone has to go through on their own. "
