Have you ever left behind one of your shopping lists at the grocery store? Well, author Hillary Carlip might have picked it up. Ms. Carlip has been collecting these discarded lists for years and she's turned them into a book called A la Cart: The Secret Lives of Shoppers. Ms. Carlip says you can tell al lot about a person by his or her shopping list, so she imagined each character based on her observations.
The Wall Street Journal's Bob Hughes goes shopping with the author in this interesting video.
