"If you go around a time when you're hungry, around mealtime, then you have a desperate search to find something to eat and you have this interplay between approach and avoidance. You go in a place, you smell, if it doesn't smell so good you go to the next place, you look at all the people, they're happily eating, and then you choose that place. So having to reconnoiter, having to go on a kind of treasure hunt for food is one of my favorite things."
