My mom has been on a mission lately to put together all the puzzles in her closet. She said she’s trying to verify that none of the pieces are missing before she sells them or gives them away. So far, she’s been incredibly lucky and everything was accounted for…until this last puzzle. She got 999 pieces into it only to discover that the last piece was gone. She searched everywhere for in case she’d dropped it or the dog had decided to put it under the couch cushions to jack with her. After it didn’t turn up, she contemplated making a piece out of cardboard to fit the empty hole. When I asked her why, she said she needed closure. She couldn’t sleep knowing there was a puzzle out there with a missing piece. I told her to cross out the 1000 on the box and put 999 instead. Then, she could market it as a feature or a challenge, if you will.
