You have just been invited to a barbecue! It's being hosted by two of your roommates. You're not terribly close with your roommates, but they are rather nice. You'll only know one other person at the barbecue besides your roommates. They're making all the snacks and desserts, and bringing all the meat. You're on your own for drinks. Oh, and they also want you to pay $7 if you want to come. Your roommates really want you to come. There's an...uncomfortable amount of pressure for you to go.
