My dad got very sick and had dementia and was difficult at night because he would get sundowners and be somewhat mean and mom would call me over to try to calm him down. His last years were very painful and was continually in the hospital with urinary tract infections.
Then mom went blind and she went downhill fast.
They both died the week before Christmas of 2023. Dad was 97 and mom was 92.
I miss them, but I am glad they went within a few days of each other.
