Once, while he was deeply immersed in some important paperwork at dinner, I put a cookie on a plate in front of him just to see what would happen. He glanced up at me, glanced back at his work, whispered a quiet thank you, and ate the cookie with a knife and fork. He didn’t even seem to enjoy it. This, needless to say, makes him the polar opposite of Kenji, who loves to eat everything, all the time, and who later told me that watching Warner eat a cookie made him want to cry.
