I'm reading the memoir Dream Catcher by Margaret Salinger (daughter of J. D. Salinger). In this paragraph I have some difficulties:
While the war was often in the foreground of our family life, it was always in the background. It was the point of reference that defined everything else in relation to it. […] As long as I’ve known him, my father has never taken being warm and dry and not being shot at for granted. […] The constant presence of the war, as something not really over, pervaded the years I lived at home.
What is meant by "my father has never taken being warm and dry and not being shot at for granted" (it is bolded in the text)?
