We hadn't realized that Yoko Ono published a sequel to her enduringly wonderful Grapefruit: A Book of Instructions, written in 1964. Acorn's conceptual 'instructions' seem more overtly focused on healing and personal change. We are especially intrigued with Cleaning Piece III, wondering what it would be like to NOT say anything negative about anybody. Would it change how we think? Susan Timmons actually tried Ono's practice, taping the instructions to her fridge. She described its effect: ...After several days' attempts, I began to seriously worry about my character. It seemed I couldn't even get past 9 a.m. ... I worked hard.
