Sarah has always implied that Nana needs her and Sarah is a saint for taking her out. Yet when she sees her she doesn't do anything practical - no dropping off shopping or taking her to the supermarket to do a food shop. No help with doctors/hospital appointments. Nana has been out with Katrina, who lives very close to her - she even took Leah with her on holiday to visit the Inghams in Portugal.
During the lockdown Sarah acted like Nana was all alone, but never once took her any shopping to drop off at the door. When single adult households could form a bubble with another household, it wasn't with Sarah. And let's be honest the Inghams didn't care about following any rules anyway so if they had wanted they would have carried on seeing her, it just gave a convenient excuse not to. Her mobility may have worsened since then but at the time Sarah was talking about her as a frail old lady not able to do anything, she took herself off to visit other relatives without even telling anyone.
Sarah forgets what lies she has told and doesn't realise with the stories she tells that she can't come out of it looking good. If Nana is so reliant on her, what is she supposed to do if they have moved to Dubai, what does she do when they are away for months at a time?
My mum and mother in law are far from being dependant on anyone for help, both are able to get out and about and do whatever they want - and frequently do. My mother in law still has a job. But we still help out if it would be useful and would do more if they needed it. We live closer to my mum so it's usually lifts if needed, offers of any shopping in bad weather/illness. My mother in law lives alone and does not drive so my husband and all his brothers make sure she gets regular trips to the supermarket to stock up on heavy things so she just has to get top ups and fresh food for herself. She has 5 sons, they will not let her spend money on taxis or struggle carrying heavy things whilst walking, for something they can easily do for her.
They certainly do not need daily help and wouldn't want it, and I would never imply that they do but there are always things to do to help out from time to time, Sarah doesn't even provide any basic help for Nana yet likes to say that she is all Nana has in the world. I would also never try to imply that I am the only one able to help - I have 3 brothers who will all help equally if needed and I would be the first to tell them if they didn't. Is Sarah really saying that she will happily see Katrina and doesn't care that she would leave Nana housebound? We all know it's not true, Sarah would never be doing all the work.
if that's true and she's the only one that bothers how does that poor dear get food etc
