My 87 year old father and I have moved into the same house in the last several months as the family realized as he was aging and still fairly able, now was the best time for him to have someone close by.
I have one sibling who lives in Malawi, Africa. Between us we have 8 adult children and there are spouses and great-grandchildren for him to enjoy a little more easily with the move. My daughter and her family lives closest, but her children are very young. She does offer to spend time with my Dad.
His health is fair to poor. His hearing is bad. His eyesight prohibits him from driving distances or at night. When we relocated, I realized it would be difficult to get a full time job with the number of doctors' visits for his heart, eyes, etc...
We used to get along well. And we still do for the most part. However his inability to hear and remember and his thinning filters and occasional unkind words are making it hard to adjust to this new stage in our lives, for both of us.
