Kristin,
To take the time to assess the value and beauty of someone whose life has touched ours, who we admire and love even more as we watch them struggling with end-of-life issues; and to share with others those thoughts, is a small portion of our own life well-spent and becomes a kind of prayer of thanks to God for this precious gift we have been given.  You are blessed to have your grandmas live so long so that you can appreciate them now in a mature way.  Thank you for reminding us about what really matters as we prioritize our time.
Joi
