I’d rather not say what I do
Men, it’s better to just come up with some answer to the, “So what do you do?” question, then to state that you don’t want to tell someone what you do. When you do that, she assumes that you do something embarrassing or illegal, or that you’re unemployed. She doesn’t assume you’re rolling in money and don’t want her to dig for gold. In case that’s what you were thinking.
