It's The End Of The World!
I recently watched a post-apocalyptic film in which the protagonist awakens to find breakfast prepared by other "survivors" in his own home. He loses it (for various reasons), but what sets him off is that he was "saving that bacon." The chilling thought of a world without bacon resonated with me, long after the movie was over.
SO - It's suddenly the end of the world as we know it. You're alive, but stores, restaurants, etc. are gone. You only have what's in your house RIGHT NOW. What do you eat? What do you save, and why?
