In fact, I refused to write this article because it is different from other pretentious articles. This is an autobiographical article that is simple and unpretentious! Is there a kind of person around you? How can I put it... Sometimes the mentally retarded person wants to beat her to death! But they are true friends who are indispensable in your life. Yes, this article mainly writes about the mentally retarded things in the lives of the author and my mentally retarded friend. My friend is temporarily named Xiao Z (I don't know if she will beat me if she finds out)
