How would you interpret this sentence? “Do you happen to know his income?” “For goodness’ sake. He’s a writer. He couldn’t say himself what it’s going to be, month to month. Do you know what books people will buy next year?” How would you interpret this sentence: He couldn’t say himself what it’s going to be, month to month? Did the speaker mean ‘he’ couldn’t know how much he would earn next month? PS: The first speaker was from FBI. And the second one was a secretary of a writer. They were talking about the secretary’s boss, the writer. Thanks! And it’s from The Lacuna by Kingsolver.
