One of his posts involves the book pictured, and Garth gives this report:
Manhattan bound 2 Train, Winthrop to Grand Army Plaza Jackie felt caught with "trash." As soon as I asked her if we could discuss her book, she started laughing. She was reading The Undomestic Goddess, by Sophie Kinsella. "It's an escape," she called her experience of reading the book, which was recommended by a friend. "It's about a woman who quits her job as a lawyer a job as a house keeper, even though she can't cook and clean."
So, if you don't want to be caught with trash, don't read where this guy might be lurking!
