What do these quotes mean?
“he drove down n. m. 53 toward zuñi a little faster than he should, the mood bothering him because he could find no logical reason to explain it. why resent this assignment? ” (chapter 2)

“o. k.,” leaphorn said. “then has he got any other friends there at school? anybody else who i should talk to? ”
“no friends there at school,” cecil said. “they’re zuñis.” he glanced at leaphorn, to see if he understood. “they don’t like navajos,” he said. “just make jokes about us. like polack jokes.” (chapter 3)

The first excerpt means that a man was allowing his mood to interfere with his actions. In the text we can see that the man is bothered with something that makes him angry and this makes him drive faster than recommended. Even though he doesn't know what left him like this, his mood is not normal.

The second excerpt means that there is a case of prejudice between two groups of people, which prevents friendships from being made and that some jokes, which may be offended, are said.

Explanation:

In the first excerpt we can observe the influence of our emotions on what we do, which can even put us in situations where we don't care about the risk we run. These emotions may even arise for no apparent reason, this will not change the potential for influence they have.

The second excerpt shows how cases of racism and prejudice prevent good opportunities from being realized. This is because it prevents people from making wonderful friendships that will contribute to different moments in our life.
