"one of those black families"??

Rose
So my friends and I  were conversing and I  was telling them about my day in Manhattan.  I told them I went shopping at Tj Maxx and Burlington, then went to whole foods before going home.  Then they (jokingly?) said that my family is one of those black families that act white because I shop at those places. Like, I didn't know going to those places made you white?  Ugh mildly annoyed. 
P.s.  This conversation was between me, my Muslim friend (girl) and my Dominican friend (boy)
