"They want us to give up another chunk of our tribal land. This is not the first time or the last time"

In this quote, Sitting Bull is expressing disappointment and resistance towards the idea of giving up more of their tribal land. He indicates that this is not a new issue and it will continue to be a repeating issue for their tribe. The use of the word "another" suggests that they have actually currently needed to give up land in the past, and now they are being asked to do so once again. This highlights the continuous battle and injustice dealt with by Native American tribes in concerns to land ownership. Sitting Bull's words communicate a sense of determination and defiance, as he refuses to let go of their land and their way of living.
