Hello. Although You have submitted a text, You have not submitted any questions about it, which prevents me from giving you any answers. However, I will tell you what this text means and I hope it will help you.
This text is an excerpt from "True West" written by Sam Shepard, where we read about the dispute between two brothers. Those brothers are Lee and Austin and they're competing over who can write the best Western theater play.
In the excerpt shown above, Lee is claiming that he can write about the real western, escaping the stereotyped myth that western theater plays present. That's because Lee has lived in the Wild West and knows what he was really like, so he believes he can write a much better play, real and full of success.
