My Wife's Grandmother.
A little less than three years ago my wife and I moved into her grandmothers home to help her out with day to day stuff and help keep the house from permanently falling into the hands of the mice. She was 90 yrs old and wasn't able to safely do it on her own anymore. In addition, we took over all of the expenses of the home (other than the property taxes). The house was built in the early 1800's and has been in her family since about 1853. When our child is born later this month it will be the 7th generation to live under it's roof. Shortly after we moved in, she had a fall, and then was diagnosed with CHF.
Now things are very difficult. It is nearly a total care situation. She is able to feed herself and has no dementia. But she is depressed and bitter and not very thankful for what people are doing for her. She feels like a burden. If we weren't there, she would have had to sell the house and move into a nursing home. That is, if she hadn't burned it down trying to make jiffy pop on the stove. Or the leaking roof hadn't fallen in on her. If she would just appear grateful once in a while it would be so much easier.
