No back story but I live three doors down from two sisters both in their sixties and in poor health. One sister has arthritis and gets quite severe flare ups which leave her in bed for days at a time. Both sisters catch the bus into town everyday to shop etc. I'm currently on maternity leave so can be at home at different times of day. Sister with arthritis has had flare up and is in bed. Other sister has flu so I offer to walk the dog and so some shopping while I'm doing mine until they are both better then take sister who is no feeling better into town one day to do her shopping. One week later I received a text message asking if I can walk the dog today, which I can't then the next ay big sisters hanging around on the street hinting at a lift to town. I take them as I'm going that way anyway then they call me about 1pm saying that they missed the bus home and could I come and get them. I answered that I wasn't available (partly as I can't be bothered and I don't want this to become a long term committment) and they get back and see me at home staring through he window as they go past. They bring the dog round that afternoon and ask me to walk it. It's a lovely staffy but very bouncy and difficult to negotiate with the baby buggy. My own dog is not keen on other dogs so I would have to do two would dog walks but walks nicely next to the buggy. They keep hinting and I keep making polite excuses AIBU not to help? I did this as a one off because they were struggling it puts me off helping anyone else.
