At a research talk this afternoon, a woman seated in the row in front of me had a paper cup of milky coffee and three Oreos. She picked up an Oreo with her right had, reaching across herself for the cookie that lay in a folded laboratory towel beside the coffee. She dipped the Oreo in the milky coffee and bit from it a small oval. Again she dipped the cookie and bit another oval. She had fine fingers and with two fingers and her thumb on the cookie, dipped the remaining piece in the coffee to saturate at least a corner before eating it. She ate each of the next two Oreos in exactly the same precise, delicate manner. When the cookies were finished, she lifted the paper cup in her right hand to take a drink of the coffee. She set the cup down. She made a few notes about the talk with her left hand on the pad of paper she held in her lap. She reached again with her right hand for the coffee, lifting it as before when her cell phone rang. Startled by the ring, she sloshed the coffee on her hand, the tan liquid ran over her thumb and down the back side of her hand, as she replaced the cup and reached for her bag and the phone, which rang and rang.
