No,definitly Dont start 'popping in for chats', or 'asking if they need anything' when you go shop either- Not trying to be mean- but thats how you get roped in to the helping on a regular basis! And as different people have differing views on whats just being neighbourly and what is too much, then its hard, but if you start any of that then you are doing exactly what the bossy neighbour wanted in first place!- A chat would be ok say if you were both out in respective gardens, or in the street but i would not go 'pop in' to their home on a regular basis- or it will probably snowball from there.And you're not up to that,so if bossy neighbour mentions it again, say (again) that you arent in a position to do so,but ask again about their daughter- ask if she actually knows the others are all doing this? She needs telling,because if the couple need so much help,then maybe either the daughter needs to organise proper care, with social services if they qualify,or paid help/care if she can pay for it- or wether she needs to start considering if they need to be living in a sheltered housing accomodation of some sort if they're so frail etc.? Its sad, but if all the other neighbours are elderly too then its safer all round if the daughter knows and fully understands how they are managing,or what help/care they do really need.It could be that she knows nothing of all this extra care they are getting from all their neighbours, and she is asking her parents when she visits "are you ok? & for pills,shopping,appts etc?" And they are just replying,"yes we're ok"- and she then thinks they are still managing by themselves under their own steam. She needs to know, to organise carers,nurses,hospital transport too for appointments.etc.(could you intercept her one day when she visits,and explain how yourselves arent in a position to help like the others do, due to health issues,but that youre concerned that they might need proffesional care instead?) Its her duty, not their neighbours.Like someone else said,they are stopping them getting the proper help & care that they need & are entitled to.Listen out for if they're banging on the wall for Help if they've had a fall or something,in a real emergency,or if they knock on your door asking if one has collapsed or something,but apart from that, you really need to take care of yourselves.
