My Mom would rule the roost and she did an excellent job maintaining a budget, watch their spending, kept the house nice and did all the cooking. As my parents aged into their 90's, Mom was still the head of the household and Dad would go along with her decisions because of past performances.
As Mom aged, I didn't realize that behind the scenes that she was having memory issues, and not making the best of decisions.... such as not allowing my Dad to use his rolling walker inside the house, it was in the way. Mom wouldn't use a walker, so she depended on furniture/wall walking inside the house.
I recently found that both my parents were reusing their Depends/Poise, guess this goes back to the Great Depression and getting your money out of each and every item, not wasting anything.
With food I recently realized she was sharing frozen dinners, such as Stouffer Stuffed Peppers [two per box], Dad would get one pepper and she would get the other one. One day I noticed lunch was an omelet but it looked like Mom used only one egg for the both of them. No wonder the both of them were losing weight.
Couple years ago I gave my parents a brochure on a very nice retirement community. Dad liked it but Mom refused to even preview. Why move, they were doing fine in their large home. They were still able to go outside and rake 20 lawn bags of leaves.
I even tried to hire caregivers to give Mom a break from all the household chores, she refused. Same with getting in a cleaning crew, to which she was insulted that her house needed cleaning... oh dear, I was just trying to help.
Fast forward and Mom is now in long term care after a serious fall... if only she would have used a walker or had moved some place more user friendly.... Dad has the caregivers back, he's gaining weight, and is improving on many levels.
