I have a friend who can look at your bookshelves and tell you your life. It’s uncanny. She reads them like fortune tellers read your palms. She once averted a friend’s divorce just by noticing a copy of Anais Nin’s 'Henry and June' on her coffee table.
She claims you can ‘read’ people (pardon the pun) through anything if you pay the right sort of attention: their clothes their pets, and – this is where I got really interested – their houses.
