A friend suggested this exercise: go to your Amazon orders page, and see what the very first thing you ordered from Amazon was.
Memoirs of the turn of the previous century are filled with the family's first automobile, its first water closet and electric lights. But I have no memory of my first interaction with an invention that is still reshaping how I live--more and more, Peter and I are now ordering groceries and toiletries from Amazon.
Apparently, however, on May 21st, 1998, I decided to order two books from this newfangled Amazon thingy I'd heard about. Perhaps appropriately, they were The Moon is a Harsh Mistress and Miss Manners' Guide for the Turn of the Millenium.
