She is normally very quiet and keeps to herself, but occasionally her delusional side comes out and she wants to start arguments about nonsense. I try not to get upset, but she just goes on and on and keeps getting louder. I just keep repeating I'm sorry but I don't want to argue. Should I just ignore her and pretend I don't hear her? My cousin, who is a nursing home LPN said to try and change the subject, but she doesn't listen....she just keeps repeating the same things and talking over me. Sometimes I just have to walk away and go to my bedroom. Last time she was standing in the same place when I came out, waiting to start the argument again. It's so frustrating talking to a person who is just making things up to argue over.
