Sorry, posted too soon. Bearing in mind, these coming months might be the last months you spend with your DF whilst he is still recognisable as himself in his own personality, do you really want to spoil these months with petty arguments about where you’re eating for breakfast?
You’re making a rod for your own back anyway. No matter what petty battle you win this time you will have ultimately lost the war. Being unhelpful and insensitive to a carer and the needs of the person they care for is the best way possible to have your relationship with both of them limited.
When you care you make decisions on what you are going to do, how hard it will be and if it’s worth the inconvenience and work. If you make things difficult for DF and SM and are unhelpful you are going to go straight on the list of people who can visit them at home, but can’t be depended on as supportive for holidays and days out. I hate to break it to you, but DF is going to be less and less aware who is around and what they are doing so very soon it won’t be a great bother to him and it’s you who will suffer most.
By all means take Companys advice if you wish, but if it leads your SM to believe you are incapable of understanding your fathers needs or taking care of them, don’t blame us if you only get to see your father for a cup of tea in his living room and are consigned to the group of people written off as ‘don’t understand, not safe’.
I know that if that happened in my family, someone refused to empathise that we had different needs for eating, flight times, etc, etc, we would not do things in future that needed support from our companions to work.
Sorry if this sounds harsh, it’s not a personal attack. Just I know from harsh experience there is little time to waste giving people second chances to be supportive and the fallout from travelling or going out with unsupportive people too great to risk many times.
