Mom - in 2001 at 86. She and my dad always had a couple of cocktails before supper. She got up to go fix dinner, and he went to the bathroom. Said he heard a noise, and went to see, and she was down in front of the stove. 911, CPR, etc., etc. to no avail. Doc said she was probably dead when she hit the floor. It devastated my dad, they had been married 66 years.
Dad - in 2002 at 89, 9 months after my mom died. He had survived several bouts of cancer, prostate and colon years earlier. The death of his wife sent him into a tail spin, and the prostate cancer returned after 20 years. Basically 9 months of providing care, with in home several days a week, to assisted living, and transition to hospice.
While my mothers' death was a devastating shock due to the suddenness, one has to be thankful she didn't suffer or linger.
Dad's death was torturous for everyone, and when it came it was not a surprise, but in a way welcome in that he was no longer suffering.
They are both buried in the same plot at the state Veteran's Cemetery, about 10 miles away. I've been once or twice usually in conjunction with Memorial Day or Veterans Day. They are not there, they exist only the memories of the living.
I don't want to seem harsh, but life goes on... take the lessons these people provided and move on with your life and enjoy life... that is what any parent wants for their children.
