Neighbor 83 living alone, and daughter is to busy to visit. I called about 6 months ago because her car wasn't home for 2 days just checking to see if she was ok. My husband and I live at 55+ apartment community. I have brought her food on different occasions, trimmed her bushes, brought in groceries for her since she moved in 2 yrs. ago. She keeps coming up to us on our porch and screaming don't call me again. Calling me noisy, calling my husband snoopy(can't hardly walk which she said poor (his name) can't walk repeating it ugly tone, pointing her finger at her head and telling him she forgot he ain't all there. This all started 3 weeks ago. Seems like some dementia since she is 83. We have tried not speaking and speaking. She walks her dog in front of us every morning. Noticed she wouldn't speak after I called 6 months ago but didn't think about that making her mad. Just kept helping her and bringing food over. We always said good morning to each other when she walked by. Now she says "Good Morning" everyday rudely, walks her dog and comes back doing her name calling and saying "do not call me again". We tell her we will stay here and she can stay on her side. Yes ma'am. She just won't stop ignoring her or speaking good morning. Need some guidance please!
