Miley Cyrus owned 5 cats. One of her cats named Tabbytha ran away. Miley was so upset that she went around her neighborhood in Northridge stapling to trees posters with Tabbytha's picture and offering a $500 reward for the safe return of her precious cat. Adam Levine was walking down Ventura Blvd. in Encino and saw Tabbytha. When he bent down to pet the cat, he noticed Tabbytha's collar with the cat's name and Miley's phone number. Adam called Miley and returned the cat. Miley was so happy that she forgot about the reward and just gave Adam $20. Later, Adam was talking to his good friend Professor Samuels and told him about finding Tabbytha. Professor Samuels asked Adam if he had received the $500 reward that Miley had offered. Adam said, "NO," and became suing mad. He brought an action against Miley in Small Claims Court for $480. Who should win this lawsuit and why?
