My wife and I helped an elderly neighbor with hundreds of hours of our time for the last 4 years i.e. helping her: refinance her house, income tax, driving her to doctors. soc. Security problems, picking up groceries, etc. We never accepted any money (or wanted any). She did give my wife several pieces of jewely over the years (nothing too expensive). Now she's mad at us and wants them back. Are we obligated legally? Thanks.
