Zitkála-Šá wrote "side by side" to show his skills and talents in relation to writing and speaking. This is because, because she is indigenous and a woman, she was constantly underestimated by students and great academic names, who doubted her ability to reason and write something so remarkable and punctual. With "side by side" she won a public speaking contest and established herself as a great thinker and writer.
