Astonished by my lack of self-control, I throw the bag out the window. This decisive action makes me feel a little better, and I resume my daydreaming. My mouth begins salivating and my fingers twitch compulsively as if digging through an invisible pile of salty snacks, but I restrain myself. I vow that as soon as I get home, I will cook up a healthy dinner of rice and broccoli to get this taste out of my mouth. It seems like a good plan, and just the idea seems to calm my craving. Finally, I pull into my driveway and park the car. I get out and start walking toward my front door--but then I realize something is wrong. This isn't my house at all. This is Safeway.
