Send a story. My friend asked me where I copied it. How should I reply?

You sent a speech on qq space, and then a friend saw it and asked you where you copied it. Then my friend may think that this conversation you sent is too good and exquisite, and the language expression is also very good and moral, so my friend has some feelings, that is to say, your conversation may not conform to your previous style, and you may not be able to publish it, so my friend doesn't quite believe that you are a joke. Maybe you still have a good relationship with this friend, so my friend can do it. So if you plagiarize, it's better to tell the truth. After all, honesty is the foundation of being a man, and it is still a very good choice to communicate frankly with friends. You can refute your friends without plagiarism, of course, in your joking tone. Otherwise, it will hurt feelings, which is not cost-effective. Then you can explain your words in detail, open your eyes to your friends and show more dignity in front of them.
