My mother died last night.
At present only my wife's mother is still alive of our parents.
I found the worst thing in all three deaths was the last time I saw each of them. They were a mere shadow of the people they had been.
The saddest thing I found last night was thinking of my two sons. They only had one grand parent to visit now. They used to love to tease my mother as grandsons as do.
The worst thing I have found is my memories of both my parents and my wife's father is the last time I saw them. As such it is not pleasant.
Thanks for those people who have have sent their condolences. Much appreciated.
