When I was a kid I used to play little neighborhood war games. Did you watch Toy Story? There was the scene when the little toy soldiers are marching off on their mission and one of them gets injured and he bravely tells the others to go on without him. And of course the others will have none of that and drag their wounded buddy to safety. We'd role-play all kinds of heroic scenarios like that. As I got older, I found that in my own private imagination, my fantasized roles of playing the hero were more like these situations you described. I would imagine that I was Schindler and harboring a whole factory full of people from persecution. Or that I was unsuspected leader of an Underground railroad that ferried people to safety. Or better yet, that I was the suspected leader of an underground railroad that managed to dodge capture. I wonder if any kids out there play games like that? For me, they didn't start occurring to me until I was older and so they've just been my own little Walter Mitty fantasies. I haven't been in that situtation and I hope that I never do have to face anything like that. But if I were there, I hope I'd have the courage I like to imagine myself to have.
