Your food arrives in a few short moments. Your health nut friend adores your choice of food, the other could care less. The friend that ordered the mac and cheese got a large, steaming, cheesy bowl with a plate of fresh fries. You look down at your plate, which is already empty because it was a small salad. You're still hungry. You watch your friend eat and you feel deep regret. You want to order more but that salad was already 20 dollars. You feel hungry and sad the rest of the night.
