I like the story Patti tells about when they used to go to the Whitney Museum. They were so broke they only had the money for one ticket, meaning only one of them would go in, look at the exhibits and report back to the other. On one occasion, Patti went inside and could see Robert through the window, leaning against a parking meter outside. When she came out, he said, "One day we'll go in together, and the work will be ours."
