My question is: How would you know? If the cheese is in his pocket you would only know about it if he chose to show you.
Oh, by the way, I DO keep cheese in my pocket. Sliced cheese. It's flat, so it's perfect for transporting in a pocket. And the warmth of your body heats the cheese so it's nice and tasty when you finally eat it. Some days before I make a sandwich I will stick a slice of cheese in each pants pocket. Five minutes later, they're good and warm.
