Indeed, this is a storm not to be trifled with, we will see how bad it truly gets.
Reading your description of you mother and sister, reminds me of my Mother, Grandmother and others in my family that had all been blessed with long years. From memories of the 1870's to the 1930's, I was privileged to be taught and regaled by elders that set the tone of my existence. As a timber wright and indigenous skills teacher, I find every day their lessons priceless. I'm just beginning to realise just how rare people like your mother, and others are. There are so many "bottle necks," of oral traditions forming, that I'm afraid when we pace, much will go with us, and the only hope is the "hunger," for traditional knowledge from so many young people.
