The era of the cowboy really began after the Civil War ( 1861-1865 ). During this decisive war the Texas cattle had roamed undisturbed in the wild, breeding freely on the plains and greatly increasing in number. By the end of the war, however, Texas was filled with wild cattle. The people in the mushrooming cities of the East and in the Middle West wanted more meat for their diet and local farmers could not keep up with their demands. Therefore, the need for the cowboy emerged from the demands of the people and the nature of the culture.
An image of American folklore which has inspired songs, stories, folk tales and legends has been the cowboy. These romantic figures of the wild frontier probably can trace their origin back to the time of the Spanish conquistadors.

A major sociological theory known as symbolic interactionism offers some important insights into how men and women are taught to fill different roles in society. The key concept in symbolic interactionism is that communication makes a big difference in behavior: people act on the basis of messages they receive from others, and how they understand those messages. This can be seen in a concept developed by sociologist Charles Horton Cooley known as the looking-glass self.
By the looking-glass self, Cooley meant the self-image that each of us develops according to the messages we receive from others; we think and behave according to our understanding of those messages.

Similarly, if she is told that she is not good ( or not
