You don't want to see your friend again, because you have already met him, don't you? (Who knows how to change it? )
I am glad to answer your question, and hope to adopt it: the solution to the problem is to change the rhetorical question into a declarative sentence, add "don't" before the sentence, add "don't" at the end of the sentence, change the punctuation from a full stop to a question mark declarative sentence into a rhetorical question, remove "don't" before the sentence, remove "don't" at the end of the sentence, and change the punctuation from a question mark to a full stop. You won't be reluctant to see your friend because you have seen him. By the way, this is a double negative, not a rhetorical question. I hope the answer is useful to you.
