I have a neighbor who lives two doors away. She is in her early 80's or so and has always been a little odd. We have 'known' each other for ten years and her reputation is that of having always been difficult. Lately, though, she seems to have singled me out and approaches me or stops her car to talk to me if I am outside in my yard talking with another neighbor. She will act peeved that I don't drop what I'm doing and engage with her, although I really do barely know her. The other day when I was walking my dogs, she ran out of her house and asked me "are we ok?" "are you ok?" "where do you go to breakfast?" "we need to go out together", etc. I suggested we go, the three of us, for something to eat with another neighbor whom I thought was sort of a friend and who is a good friend of mine. She began saying this other person owed her money (I talked to the other woman who is a good friend who explained how 'crazy' this lady is and this is not so and I do believe her), rolled her eyes about her and clearly didn't want to do that. She also recently got married to an elderly man who had been living with her for a while. I suggested then that maybe 'the four of us' (my husband, her husband and we) go out to eat together. She said she just wants to 'leave them at home and we can call them later'. I said, well, we'll see and then another neighbor drove up and it broke up her ability to engage me. I told her I had to go inside. As I said, I barely know her but she clearly has dementia and at the same time, seems very manipulative and smart enough to 'triangulate' situations. I am feeling stalked in a way. She will drive down the street, see me, and stop and roll down her windows and just kind of stare at me, waiting for me to say something. I keep it short and polite and keep walking most of the time. I do not want to be cruel or rude to her but I also do not want to encourage her. She seems hell bent on us being friends and I have never given out the signal that I want that. Not sure how to handle this. I have been thinking about talking her her husband but I don't know him either and just by virtue of the fact that they recently married, I doubt he thinks she's mentally not 'there'. Other than hiding in my house I don't know what to do with this. I really do not want to go 'out' with her and will have to just tell her that, I guess.
