Jessica and Dana are roommates. One night while Jessica was at work, Dana was hungry, and although there was some leftover pasta in the fridge, she ate Jessica's last frozen meal instead. Dana reasoned that Jessica owed her one, because Dana had done Jessica a favor by picking up things for her at the grocery store, even though Jessica had given Dana money to pay for the things. When Jessica got home, she went to the fridge to warm up her frozen dinner. When she saw that it was gone, she was very angry, and accused Dana of eating food that wasn't hers. Dana, for her part, got angry in return and thought to herself that Jessica was just a stingy person who didn't like to share. Despite the fact that Dana was angry, she did not yell at Jessica but instead apologized and offered to drive to the store right then and there and buy another frozen meal. Jessica agreed that Dana should do that, so Dana did drive to the store and returned with a frozen meal.
