After A went to bed, we broke out the Indigenous Peoples Puzzle. Our Columbus Day tradition for the past three years has been to do the puzzle, which is an illustrated map of pre-Columbian North America societies, and talk about the different cultures represented and what happened to them. This year involved less discussion (C was cheerily humming while he did the puzzle, and he's been so contrary lately that when he's happy we savor the moment and avoid changing anything) but it's always sobering to see the names that now only exist as place-names if at all.
