<p>Well, if you said “Yes,” that would mean you would also say yes to the person who asked you for dinner. If you said “No,” that would also mean you would say yes to the person who asked you for dinner.</p>
<p>If for example:
"would the answer to this question (Answer: No) be the same as your answer (which is No too)?
Wouldnt that make it a possibility to say yes only, as they are both the same?</p>
<p>If you answered that question “No,” then that means the two answers would be different. Since you have already answered “No” to the first question, that means you must answer “Yes” to the person asking you for dinner, in order to make the answers different.</p>
<p>If you answer the first question “Yes,” that means the two answers would be the same, so you must answer “Yes” to the person asking you for dinner, to make the answers the same.</p>
<p>So, you have to answer “Yes” to the person who asks you for dinner, but as for the first question you can answer it either way.</p>
