Nadia (6:15 P.M.): Study group is still at my place at 7, right? Should I order pizza? Ben (6:18 P.M.): Yes! But Carla is vegetarian, so maybe get one cheese pizza too. Nadia (6:19 P.M.): Good idea. They're $12 each. I'll order two, and we can split the cost. Ben (6:21 P.M.): Perfect. I'll bring the drinks.
