In olden times, you'd wander down to Mom's Cafe for a bite to eat and a cup of joe, and you would feel right at home. It worked just fine if you never left your home-own. But if you went to the next town over, everyone would look up and stare at you when you came in the door, and the Blue Plate Special would be something you didn't recognize. If you did enough traveling, you'd never feel at home anywhere.
