Very nice day, with excellent food and relaxed company. Got very involved with a jigsaw puzzle late into the evening. It's after 1am now. The puzzle is difficult. It's a maze, with all the pieces cut the same shape. Assembled correctly, you must be able to get through the maze. There's lots of green. I pitched in and took the approach of organizing the pieces in ways that emphasize their differences, hopefully making it easier to search for fitting pieces. For instance, I put all pieces with one green nibbed top together, all with a green nibbed top and green left side together, etc. This leads to searching via "I need a piece with a green top and brown left foot", so I go the area with green tops and only look for the brown foot.
Blah, blah, blah! Too tired to proofread that paragraph. Reading a little Doc and going to sleep.
