My wife asked me to drive her to visit her 102 year old grandmother, whom she loves very much.
My wife whispered to her that it was okay to let go if she wanted to.
The old woman died in her sleep that very night.
I do not want to exploit this dear woman's demise as an opportunity to air my views on death and such...but will when domestic matters settle back to equilibrium.
My advice? Take a minute to tell those close to you how you feel.  It matters.
