I say: "Follow me to the sandwich shop. Let's buy a sandwich." As soon as you give the command, people all around the world begin to follow you, eager to see where you will lead them. Some walk alongside you, while others hop in their cars and follow you from a distance. You make your way to the sandwich shop, with a large crowd of people trailing behind you. When you reach the shop, you go inside and begin to browse the menu. As you decide what you would like to order, the people around you also begin to peruse the menu, trying to decide what they would like to eat. Eventually, you all place your orders and receive your sandwiches. You take a bite of your sandwich and savor the flavors, with everyone else following your lead and enjoying their own sandwiches.
