The Great Gatsby
The Great Gatsby, talked over and around
I'd like to know the meaning of "over and around" in the following excerpt from the last chapter of The Great Gatsby:
There was one thing to be done before I left, an awkward, unpleasant thing that perhaps had better have been let alone. But I wanted to leave things in order and not just trust that obliging and indifferent sea to sweep my refuse away. I saw Jordan Baker and talked over and around what had happened to us together and what had happened afterward to me, and she lay perfectly still listening in a big chair.
Thank you.
