There are puzzle pieces all over my floor

Caili bought the most impossible 1000 piece jigsaw puzzle yesterday and we, along with Dandan, who has the patience of a saint, have been working at it all day. We've probably completed about 10% of the puzzle. Have to call it quits so I can start preparing for tomorrow's class and debate (on China's economic history and post-1978 "opening and reform" policy...ugh). For the time being I'll have to deal with the millions of little puzzle pieces scattered all over my floor.
