"There are things they tell us that sound good to hear, but when they have accomplished their purpose they will go home and will not try to fulfill our agreements with them"

In this quote, Sitting Bull is warning versus blindly relying on the promises and words of others. He suggests that there are frequently things that are stated to us that might sound appealing or reassuring, however ultimately, these words may just serve the speaker's own interests. As soon as their function has actually been fulfilled, they will leave and not follow through on any agreements they may have made with us. This highlights the importance of being cautious and discerning when it pertains to making contracts and alliances with others. It likewise speaks to the concept of not being quickly swayed by empty words and rather, trying to find actions that align with the pledges being made.
