"Too" Question!

The poem "Those Winter Sundays" has the phrase too in the first line because Sundays are supposed to be days of rest, but just like every other day. The son or daughter makes it seem like she never really appreciated what the father did for the family. The line "No one ever thanked him." Has the air of guilt in it. The poem has a feel of an early morning and a lagging morning. It has the feel of getting up early and dragging yourself out of bed to do the work that no one else will do. 

The son or daughter seems like he/she regrets not helping out his father more and obviously never fully appreciated all the father did. The question at the end of the poem expresses the child's question of why he/she never noticed how much the father loved him/her. The father seems austere and obviously did show a lot of love to his children through sympathy or through loving words, but helped and showed love through everyday acts of love. Like shinning the child's shoes.
