Not interested in a hearing test (or hearing aid), withdrawing from all conversations (unless one-on-one) & insists everyone talks too low. Gets aggravated with me & raises voice/yells at me because she doesn’t want to talk about her hearing, the way she walks (short steps, almost like ice skating), doesn’t want me to even SUGGEST her attendance at local senior center (lots of activities). She doesn’t want to be with ‘those old people’. I’m concerned as she eats most meals out at local diner or restaurant. She talks about waitstaff as if they are her family, stays there as late as 11pm & has asked me to end my visit so she can ‘go get something to eat’ at the diner. I’m concerned as she doesn’t use 15-20% tip rule (gives what she feels like & doesn’t care, even though she has reverse mortgage & doesn’t have any money) and talks to waitstaff about my family’s personal affairs (like waitstaff are her confidants or close personal friends). I’m concerned as she doesn’t have personal boundaries, and literally starts to talk to EVERYONE she meets at the store, getting in the car, etc. She’s never had (or has) friends & I get that she’s lonely. But does NOT want my suggestions (about local senior center) and other options to meet/talk/do things with people her age. She told my husband, while the three of us were together, that she’s “not going to listen to her” (meaning ME) about anything. How to deal with this?
