I signed it and sent it back blank. They sent another and I did the same thing.
A woman showed up at my door and said I had to answer the questions.
I answered every question with the response “it’s none of your business” She looked at me, and I told her she wanted an answer, and I gave her one to each question asked. Never heard back. That was 4 months ago. Commerce Dept IIRC.
I like it. They try that excrement with me, my answer to every question will be “42” after all, that’s the answer to the universe, right?
