The relationship between Sinesio and Faustina, husband and wife, is probably meant to represent the stereotype of a poor couple living in Mexico. The husband works like a dog all day in the city, while the wife works equally hard at home and has to take care of their three children.
Sinesio and Faustina have been married for a good number of years, so they do not tread carefully around each other's feelings. When Sinesio answers his wife's question, he does so "with annoyance." When he notes that he will have to go to the United States soon, he speaks "gruffly and with authority."
When Sinesio realizes that his wife has used the winning lottery ticket to patch up the broken window, he is "frustrated and angry" and he "lashed out at Faustina in anger." At this point, though, it is not surprising that Sinesio is upset; after all, one hundred million pesos is glued to a pane of glass on his door.
Thus, while Sinesio's treatment of his wife Faustina is certainly not ideal, it is also not surprising given the length of time they have probably been married, the state of poverty in which they live, and the anxiety of having the winning lottery ticket, which would at least solve their financial problems, glued to the window pane.
So agitate is Sinesio that he basically tears the door off its hinges and puts it "over his head" as he runs "down the streaming pathway to catch the autobus."
