These lines give really strong imagery of just how hard his mom works so that her son can have special items like his sweater. The "blue morning" makes me imagine how her shift starts even before the sun rises. Right before the sun begins to rise the sky slowly fades from dark blue to this true blue color. Her uniform still smelling like the restaurant food, despite it being washed, shows her dedication to providing a happy life for her son.

It won't let me select the line "The sweater fits like a lover", but this type of device is a simile because it compares the sweater to a lover using "like". I think the author compares the sweater to a "lover" because it fits him nicely like two people might pair nicely together. I also think he uses the word "lover" to describe how he feels a sense of comfort when he wears the sweater much like how you might feel comfort in someone you love.

What is the significance of the spacing between "patties?" and the proceeding "And twenty"? Also why did he choose to break after "And twenty" instead of starting a whole new line with "And twenty"?

What significance does the "clean strand of weave" have to do with the questions he asks? Is he wondering why his mom is willing to buy him a nice sweater after putting herself under so much physical labor?
