Ocean Vuong seems to be giving an excuse for the craft of writing, poetry specifically, by presenting what is clearly an essay cut up into what we register as a poem. So that seems to go along with the opening theme that "words" can be hampered by their "langauge," in much the same way the individual is by society. But, without these forms, there is no correspondence anyway. This chopped up essay poem form then gives us an out, a way to chop and pick apart society, at least the society we have access to changing, into something suitable for our expression.
