Sadly, although this makes me sound like a miserable twunt, I would NEVER volunteer to help people/do things for people on a regular basis. Help in an emergency yes, now and again yes, but offering regular help? No. Never.
Too many people have taken advantage too many times in the past. From expecting me to take parcel deliveries in regularly, to expecting me to look after their children/keep them at mine until they can be bothered to come for them (and not coming for HOURS after they promised,) to people cadging money and items of mine.
I have also had neighbours in the past using me as their personal gofer... Giving me shopping lists, with 15 different things they want (from 5 different shops,) and moaning when something wasn't right.
Rightly or wrongly, when I came to where I live now - almost a decade ago - I made a resolution to never offer help to anyone, and say 'no can do' whenever anyone asked me to do something for them.
One woman who moved in opposite me a year ago, started asking me to take in parcels for her (as I work from home.) She doesn't even work, she just goes out with her mates for lunch/coffee/to the gym, and expects other people to take her stuff in. I said no every time she asked, and said 'I have zoom calls with work quite often and will very likely not hear the knock.'
After 3 or 4 attempts she stopped asking. I now see the woman next to her going round to drop packages off to her maybe 3-4 times a week! (The neighbour is a SAHM with 2 kids.) So the woman who asked me, clearly CBA to go get them. So she has found her patsy. It was NOT going to be me. Been there done that. Never again.
Not very helpful sorry @Troyes76 All you can is start saying NO every time. She may fall out with you, but would that be a bad thing?
