Would love your thoughts on this. The background is there are 4 siblings including me and our 84 year old DM. Generally we all do our bit to help her albeit I do the most with hospital/ doctors /opticians appointments as I'm retired. I found out today that my sister has had a brand new car on Motability and is paying DM what she would otherwise receive in disability payments. She's done this with no consultation with the rest of us. Indeed one of my DBs suggested he could the very same thing a few years ago but same sister strongly objected. DM has early signs of vascular dementia although seems to understand this situation. I feel quite cross as I think my sister has a brand new car to swan about it but won't be doing all the running around that I do. In fact I'm thinking of stepping back and not doing it anymore. I don't want DM to suffer but she saw fit to hide it from me and my DBs so now will have to ask sister to do it all from now on. It's the sneakiness that's got to me more than anything.
