My friend Dali and I headed to DC to visit a friend whose health was declining even as he was denying that he was ill. And while we spent lots of good time with him, laughing mostly at the expense of others, we also hit many of the museums around town. This was the way the light came into the new wing of the National Museum of Art. Soon our friend was gone. And not long after that, Dali was gone. But the good memories, like art, endure.
