In the book The Great Gatsby what does gatsby do that makes nick want to get up and slap him on the back?

In the Great Gatsby, Nick Carraway is the middle man. Nick has a passive attitude and observes everything goes on between the wealthy citizens of East and West Egg. Nick does not like to make judgments about people which you learn in the first chapter when he states a quote about making judgments that his father once said to him. Nick is the narrator of The Great Gatsby and is the most normal, and down to earth person in the book.
