Tim O'brien said this quote
“ It’s a hard thing to explain to somebody who hasn’t felt it, but the presence of death and danger has a way of bringing you fully awake. It makes things vivid. When you’re afraid, really afraid, you see things you never saw before, you pay attention to the world. You make close friends. You become part of a tribe and you share the same blood- you give it together, you take it together. ”
