" Listen, sweetheart. Don't be a hero. [...] If they actually go through with this hare-brained notion and send you into the fighting, there will come a time when you'll have a choice between staying in your trench and crawling out of it to save a buddy. Or maybe you'll have had enough of getting shelled and decide you just have to run out there and shoot someone. That's what I mean. When that moment comes, you stay down. You keep your head down. You hug the ground. "
