It's a week of talking and listening, thinking and communicating. Your friends are arrayed around your table and you've got new invitations coming in all the time. All the while, many aspects of your life are undergoing great change. Sometimes returning to the simplest things can bring the greatest pleasure. Witness the grilled cheese sandwich - just Cheddar or American cheese, white bread, and butter or margarine. If you like, add slices of Roma tomato, onion, or jalapeño pepper for fun.
