How we cite our quotes:
Rose: "I got some meat loaf in there. Go on and make you a sandwich." ( 1.3.10)
It seems Rose feels her main duty around the house is to always be cooking. Every time she enters the stage she tries to get somebody to eat something. This was a role that many women fulfilled in 1950s America.
Troy: "While you thinking about a TV, I got to be thinking about the roof...and whatever else go wrong around here." (1.3.42)
Troy sees one of his chief duties as maintaining a home for his family. In this scene, he tries to get Cory to understand the practical demands of keeping the house in a livable condition. Though Troy fails his family in many ways, he does work hard to make sure they have a home and enough money to get by on.
Troy: "You live in my house...sleep you behind on my bedclothes...fill you belly up with my food...cause you my son. You my flesh and blood. Not cause I like you! Cause it's my duty to take care of you." (1.3.114)
As a father and husband, Troy feels obligated to provide the necessities of life, but he seems to think his duties end there. It sounds like he doesn't feel obligated at all to show his son that he loves him.
