Ivan, who is 17 years old, has owned, Misty, a collie, since she was a puppy. In good weather, Misty is left in the fenced-in, back yard. One day, when Ivan returns home from school, Misty has simply vanished. Despite a quick and frantic search, Misty is nowhere to be found.

Ivan immediately tapes up several reward posters around the neighborhood (with Mistys picture), offering $100 for her safe return. Some are posted outside; others are in neighborhood stores. As the weeks pass, Ivan loses hope and obtains a new dog from the Humane Society, Molly, a terrier mix.

Almost two months from the date of Mistys disappearance, Charity Smith, an elderly neighbor, finds half-starved Misty sitting in her yard. Although Charity is not aware of any reward, she recognizes Misty and returns her to Ivan at home.

Ivan is delighted and welcomes Misty but lets Charity know that the $100 reward is gone; he has spent that on Molly. Surprised but pleased that a reward had been offered, Charity politely asks Ivan for the $100. Ivan politely refuses. Charity files suit for $100. Which party is likely to prevail and why?
