Robert Is About to Graduate College, and His Parents Tell

Robert is about to graduate college, and his parents tell him that because he is the first member of the family to graduate college, they want to buy him a new, but inexpensive, car. They have the money to buy the car, and Robert is excited about getting his gift. Robert owns a used car but has never owned a new car, so this will be his first. He decides to keep his used car because he had been promised a new car by his parents for his high school graduation and never got it. On graduation day, his parents tell him that they have decided to use the car money for a vacation and there will be no new car.
