So you walk out in your neighborhood in the late afternoon or early evening, just as your neighbor is barbecuing some chicken, or ribs, or sausage, or hamburgers.
Damn - that's such a sweet smell. You want to rush over and steal a sausage from her grill.
Then you ask - "why does the smell from the grill across the street seem to be so much more delightful and enticing than the smell from my own grill?"
Does this important question have a definitive answer?
