Tim was too tired to follow Harry's movements closely. Instead, he browsed through the bags until he found a container of mashed potatoes and a plastic fork, and began to eat. "Exercise is good, I agree," he replied between mouthfuls. "These mashed potatoes are pretty good. You should try some." He held out his fork, filled with mashed potatoes for Harry to try. It was just instinctive on his part; he didn't realize that it might possibly freak Harry out to share a fork.
