My dad is constantly talking about having to sue his boss and former colleagues for harassment and false accusations of robbery. He refers to them as if he had seen them yesterday, but my dad's 83 and hasn't worked with those people nor had any contact with them in over twenty years. Furthermore, the place he's referring to is in NY and we now live in France. What's really troubling is that all the people and places he mentions do or did exist. But the harassment is something neither my mom nor I had ever heard of before. He's had this recurring story in mind for several months now, and I've tried to appease him by telling him that I would take care of it. He's asked me to draft up a letter for him, and I keep telling him that I'm working on it. I just assumed he would forget that he had asked me, so I felt that I could just keep giving him the same reply.... but he has started telling me that I give him the same answer everyday, and that we need to move forward with his case. I don't know how to handle this situation. I can't keep telling him the same thing. How do I put a stop to it? Any advice would be much welcome.
