We caught up on family news, work news, exercise news (both my parents are into it now), and how calming fish are. The Delta has a decorative water feature with room for a few fish, and we watched them for a bit. "The chefs don't come over here," I said. Mom mentioned hearing about a restaurant where patrons chose the fish they were going to eat, the way people do with lobsters. So, that time I didn't outthink the world -- someone acted on the thought long before I thought it!
(Though maybe not even Japan's "sushi train" restaurants have the fish swimming there...)
