Goodbye, Sandman. Your wit, wisdom, courage and humanity will be sorely missed. My eldest son is named Sandy*. If he turns out one tenth the man you are, I shall be well pleased.
Sending a great big granny-hug to the best damned virtual granddad on the whole internet.
As someone who has faced her own mortality, I firmly believe you have made the right decision. May your final days be filled with peace, love and joy; may they be pain-free and pleasantly occupied. Go into the great unknown knowing that you are loved and will be remembered fondly by many, many people. And know that you made a difference, a good and great difference, in the lives you touched.
Love and hugs.
*Yes, I married a Scot. So sue me!
