Explanation:

In the second paragraph of this essay by Zora Hurston, we learn how the residents of Zora's Black American town of Eaton, Florida, treated Southern whites who passed through with indifference but treated the Northerners with awe and excitement.

A development to this paragraph would be an exchange between the speaker and the visitors so that we may better understand the awe and excitement that the Northern whites were greeted with.
