A neighbour from a few houses away, has always been nosey and a bit of a gossip.
When DD was at primary, we walked past their house twice a day and they (her and her husband), would always stop to talk to us. She also spoke to my parents a lot, before dad died.
A few weeks ago, DD & I were waiting for a friend to pick us up and she came out. She said she was being nosey and asked who we were and how long we'd been here. I told her I'd been here for 14 years and DD all her life and said she should probably didn't recognise DD as she'd grown (she's 12 and doesn't look that different, but was being charitable, not sure why she didn't remember me).
I had a supermarket delivery and the driver said she was asking him for forms to get deliveries. He told her she'd need to do it online, but she said she doesn't have the internet and wanted to do it by forms. She then kept walking up and down, till he went. Same with my next delivery.
This afternoon (4pm), she knocked on my door, wearing a nightie, dressing gown and slippers. She asked for a male name I'd never heard of and know no one who lives on our road has. She then asked who I was and where I came from. I said I came from my house (as I was a bit confused by what she meant). She said not to mind her, that she was drunk! She then asked about a funeral, confirmed I wasn't the male she was seeking and went. I asked if she was OK, she said she was, but I watched her home.
I'm guessing social services would be the best bet? It would be very difficult to talk to her husband (who I rarely see, as he had a femur operation recently).
Not sure what else to do. I'm assuming dementia, unless she is alcoholic, which doesn't seem likely (and she didn't appear drunk at all, just confused).
