I'd escape through the back, and blend in with the rioting crowd, so that when we break into my house, I can try to "steal" the things that are most valuable to me, such as my television or game consoles. If I don't manage to, well at least I got out of there alive. Once I've done so, I'd retreat to my secret hideout outside of town to put away all my stash and then join a traveling train band, the types you usually see in films and cartoons, where we all enjoy our new, easy going, non-materialistic life, which has finally gained relevance thanks to the collapse of civilization, while occasionally going back to my hideout to game on my consoles.
