This is awful, stunning news to me.  I remember Carrie well -- both as a student and since graduation, as a friend whom I spoke with every five years or so -- and with whom I visited a few times in the past fifteen years.  She was so filled with life that she appeared to be glowing from its radiance.  That she is now gone diminishes our world of some significant amount of its brilliance.  Ah, I miss her -- and I'm very sad that I didn't get to see her or speak to her in the last three years.  My positive thoughts go out to her family.
