Add YoursCrooks is aware that as an African American he is isolated from the rest of the men. He can share the bunkhouse, isn't invited to socialize or participate in activites with the men, and is ostracized from the others on the ranch. Each of these things contributes to Crook's pessimism and desire to stay isolated. He keeps to himself because he doesn't feel welcome, and he reacts poorly to good intentions because he isn't used to them.

Crooks reacts this way because he is "Black" and this book is set in the 1930's (The Great Depression Era) when blacks and non-white were still discriminated. Crooks isn't invited to these outing because of him being black. All of the men on the farm are white or caucasian unlike crooks when it notes him as a "Negro stable buck" when they introduce him. There was also a lot of discrimination to black people during the great depression because 1) they were viewed as slaves and only slaves by many people. 2) Whites were not having enough farm jobs because of blacks taking them from them, and finally 3)White thpugt that they were the "superior" group during this time and wanting only the white race to be known and wealthy not the blacks(slaves).
