The world is a sad, sad place when it comes to this!
I had a lovely neighbour, over 20 year my senior. When I realise she could not get out on Sundays, as there are no buses, I started going and sitting with her on Sunday afternoons. We would watch a film together.
Then she started to become frail. She had a stroke, I called the ambulance, after using my key to get in. She came home, my DP helped with heavier shopping, although she went out every day. I visited every evening.
I found her again, having had another stroke, called an ambulance, then went back to looking after her the same way when she came home. Then again! Then, she had a stroke back earlier this year, did not come home, instead went in a home nearby. I visited her there three times a week. All this time, I looked after her dog for her.
Then she got moved to a home near her son. She died shortly after. I went to her funeral. Her family have shown me nothing by gratitude for the help and support I gave her.
I would have hated to think they suspected me of wrong doing. Yes, sometimes I would help her with some financial stuff, asking the gas and electric company not to reduce her payments in Summer as she worried about owing money come Winter, things like that.
