I agree.
My neighbour's husband was in hospital with severe dementia. This was just after my own husband had died. I felt sorry for her, because I knew what she was going through.
He son had had his car crushed - driving without an MOT and insurance.
I volunteered to take her to and from hospital, since the bus journey was so long and I wasn't working at the time.
I also took her to the undertaker when the time came. The problem was that she also wanted me to go into the appointment with her. She didn't want her sons there. I didn't want another visit to an undertaker so soon after my husband's funeral, but felt I couldn't refuse.
Then she needed to go into hospital in a hurry. I took her..but she wanted me at the appointment with her. I said one of her sons could go. No.
I finished up taking her and her two boys
I gradually managed to pull back, but I still get phone calls wanting lifts from time to time. They usually start off with "What are you doing today...?"
The last time was a trip to the dentist.
I've realised that when she was asking me about my work recently (I returned to supply teaching) she was actually checking which days I was free...
I'm not mean. I'm really not. She's not a poor old woman with no resources. Now that her husband has died, she's financially well off and can well afford taxis.
I need to keep my distance, however. Her middle-aged sons don't (officially) work. She has told me that she doesn't trust them. Nevertheless, she keeps trying to insist that I should employ them to do jobs around the house and garden.
I'm very uncomfortable with the whole situation, and I'm in it because I was too stupid to set boundaries.
