If you have answers for everything, what can't you answer?
There is nothing I cant answer
Then, I ask you the following question.
Can you answer nothing?
Nothing can be considered many different things. All of those things are nothing. Silence, at its essence, is nothing. I can reply to that. Nothing could also be asked, and yet, even if nothing is asked, I can still respond.
So my response to your question.
I can respond.
