Ah, finally the GPS got the directions, now..."
11. × Imagine go to restaurant, order burger, and pay for it  I’ve made a request for a value back (burger) × The cashier hands me a receipt with an order number on it  This order number is a promise that ensures that eventually, I should receive my burger. × So the order number represents my future burger
12. × While I wait, I can do other things, like send a text message to a friend. × Eventually, I hear, "Order 15!”, I hand my receipt to the cashier, and take my burger. × In other words, once my future value was ready, I exchanged my promise for the value itself.
13. × Promise other possible outcome: Cashier call my order number, and says: "I'm sorry, but we appear to be all out of burgers.“ × Future values: success or failure
