Whiteness is a social class because they want to be like one of American or white people. We can see from the sentence “It was your birthday. We were splurging.” Birthday falls on Goodwill had a yellow tag. It means they didn’t feel different when items were a fifty percent off tag. they feel like they are reborn as one of white people that were splurging. In addition, we can see from the sentence “Do I look like a real American? you said, pressing a white dress to your length.” white dress refers to white people. Normally, a little dog and mother always feel different from others because they are not real American or white people so they think that they bought many things or they were splurging, they were one of white people. To sum up, whiteness shows social class because they always feel different from white people but when items of white people are fifty percent off, they feel one of them.
