Here's one we got from friends of ours who were lapsed Catholics. They wanted to keep the tradition of saying grace but at that point in their lives, prayer didn't seem very authentic (and brought back some bad memories). So every night at dinner, they went around the table and everyone described one thing that made them happy that day. We've been doing this for years and really like it. Sometimes when we are all grumpy and tired, it helps get us back on track.
