It's wrong to take advantage of one's roommates.
Laura and Sara were roommates in college and Sara cooked great meals often.
Laura wants to eat the food that Sara cooked.
Laura gave Sara extra money to make up for the time and expenses for her cooking.
Laura pretended to never have enough money to eat so that Sara would give her some food.
Sara cooked delicious meals for Laura almost every day of the week.
Sara got tired of cooking for Laura all the time and started going out to eat.
