"Those Winter Sundays"

I took this poem to have two interpretations. The first is about a son looking back at his childhood. His father was a hard worker and he was not appreciated. Words like "blueback cold, 'cracked hands', 'banked fires blaze' show that his father worked a lot and in harsh conditions. The son was regretful that he never thanked his father for all that he did. Another interpretation of the poem is about God. God gave life to people. He does so many things for people and they do not always realize it or thank him for it. The phrase, "Speaking indifferently to him..." means people pray to Him but only ask for things. They do not thank God for all he does. They take and take and give nothing back.
