My partner and I live next door to an elderly lady who we do know fairly well, and has always asked us to do odd jobs which we don't mind. A few months ago she asked if we would collect her morning papers for a few weeks as her doctor told her to stop going out alone. This has turned into a few months and now she doesn't ask, she just gives us the vouchers for the newspapers and expects us to keep collecting. She is also asking us to take her to doctors appointments, hospital appointments, etc. and we don't feel like we can say no so we have been doing. I tried to broach the subject with her about maybe getting her newspapers delivered, as she always says she has a lot of money, however she just said I can get them for her at any point in the day if the morning is the issue (which it isn't, but I wasn't getting through).
I feel bad as she doesn't have any family nearby, her stepchildren live at the other end of the country, but also I feel like she is asking quite a lot of us now. My partner and I work full time and also study part time and volunteer in the community so we are very busy. We don't mind helping every now and then, but I don't really know how to tell her we can't keep doing things all the time for her. Any help appreciated!
