In Robert Hayden's "Those Winter Sundays," what seems to be the speaker's attitude toward his father now?

I like the way your question clearly points towards an
understanding of how the speaker is looking back on his childhood from the vantage point
of reaching mature adulthood. Thus it is that the poem presents us with two different
attitudes and beliefs about the speaker's father. The child that he was obviously took
his father's acts of self-sacrificial love for granted. He spoke "indifferently" to his
father, and it was clear that he did not know anything of "love's austere and lonely
offices."

However, if we think for one moment about how the
older and wiser narrator describes what his father did, the respect and love and sense
of thankfulness that he has for his father becomes evident. Note the way that he
describes the cold as being "blueblack" and stresses the way that his father, even on
Sundays, after a week of labour, would get up without fail, even though he was never
thanked for this service:

Sundays too my father got up
early

and put his clothes on in the blueblack
cold,

then with cracked hands that
ached

from labour in the weekday weather
made

banked fires blaze. No one ever thanked
him.

Such details that the
speaker as a boy had been blind to clearly indicate the way that the speaker, now he has
grown up into an adult, appreciates his father for what he did and recognises the
sacrifical acts of love that his father performed, day in and day out, in spite of his
own exhaustion, for his son.
