How does Richard Rodriguez use imagery in Hunger of Memory: The Education of Richard Rodriguez?

Imagery:

“To many persons around him, he appears too much the academic. There may be some things about him that recall his beginnings—his shabby clothes; his persistent poverty; or his dark skin (in those cases when it symbolizes his parents’ disadvantaged condition)—but they only make clear how far he has moved from his past."

“Intimacy is not trapped within words. It passes through words. It passes. The truth is that intimates leave the room. Doors close. Faces move away from the window. Time passes. Voices recede into the dark. Death finally quiets the voice. And there is no way to deny it. No way to stand in the crowd, uttering one’s family language.”
