There are some details in this poem that relate to the topic of American identity. For example, at the beginning of the poem, we learn about two girls who are friends. They look at boys together, and they are best friends at school. All of these details resemble the lives of most American teenagers. Moreover, we also learn that the last names of the girls are O'Connor and Ozawa. These are most likely Irish and Japanese. This detail develops the idea that American identity is made up of various nationalities coming together peacefully.
The answer to the question above is "his friendship with the girl with a different race than him" which Okita revealed in the excerpt above. This significant detail is clearly shown in the last part of the excerpt which described Okita's and the girl's last name. This poem is written by Dwight Okita, a Japanese-American playwright, novelist, and poet.
