In chapter 7 of the great gatsby Why does Gatsby wait outside the house?
Gatsby, Nick, Tom , Daisy and Jordan have all gone into the city to try and escape the dreary heat and boring feeling they all had on Long Island but the heat and tedium just follow them until there is a huge confrontation between Tom, Daisy and Gatsby. They leave the city and on the way home, the car driven by Daisy kills Myrtle and they arrive back on Long Island in separate cars.
So Gatsby worries that Tom is going to retaliate violently against Daisy because of their fight over whether or not she ever loved him or would leave Tom for Gatsby. In the end, nothing happens and he goes home, but he waited for a signal from her if something were to happen.
