Which word describes the tone of the memoir, barrio boy, by galarza

Ernesto Galarza ("Barrio Boy") utilizes details to make the demeanor or tone of his memoir. He depicts his new school in America in detail contrasting it with his old school in Mexico to express his feelings toward the new school. He has different emotions too: intimidation, fear, unsureness.

The details focus upon the character is coming into another school without recognizing what's in the store since he doesn't talk the dialect nor does he think about their way of life.  

He expounds on how tall Miss Hopley and Miss Ryan were offering his tone of thanks and gratification for them just as recognizing their significance in his life. His tone all through the extract we read is that of gratefulness toward this school and how they enabled him to wind up "American" while remaining Mexican.

honestly you should not write it the word placement is not right and this does not sound right so i think you should write it this way. the life lessons i refused to learn, taught me the hard way this sounds way better you should try it! hope this is very !
