Another loss

In an extremely strange symmetry, the RE also lost a sister. She had been suffering for a long time from a progressive condition, and we sadly observed this bright and beautiful lady's irreversible decline, the tireless efforts of her family to reverse her condition, and her husband's single minded devotion to her care.
We all miss her. With her passing, I try to erase the memories of the silent figure who seemed impervious to our greetings and caresses, and to remember the sister who loved and cherished us all.
Each one of us has our own particular set of memories of our interactions with her, and sharing those brings us some comfort.

This is life.
This is life.
It ends, for each and every one of us,
It will end.
Knowing this,
why does it still hurt so much????
