Quote from : World War Z: An Oral History of the Zombie War Book

...So I put it out of its misery, if it really was miserable, and tried not to think about it. That was another thing they taught us at Willow Creek: don't write their eulogy, don't try to imagine who they used to be, how they came to be here, how they came to be this. I know, who doesn't do that, right? Who doesn't look at one of those things and just naturally start to wonder? It's like reading the last page of a book... your imagination just naturally spinning. And that's when you get distracted, get sloppy, let your guard down and end up leaving someone else to wonder what happened to you.
