One day, people were lining up on the street and one person had an expensive ring on her hand. This ring was from her ex-husband and she wore it everyday. To her right was an experienced pick-pocket. To her left was her boyfriend. Once the line was finished and she got her ice cream, she realized that her ring was gone! Her boyfriend and the robber were gone too! After long hours of searching for the ring and her boyfriend, she found him feeding the ducks with some bread. The robber and the ring were never seen. Later that evening, her boyfriend took her out on a date and he proposed! The ring was completely different, though, but it still looked just as expensive as her old one. Who took the ring?
