A rose is never an argument. There is no such thing as an angry rose or a moping rose or an empowered rose; only a realistic rose, a matter-of-fact rose, a transient rose. Each flower in my garden holds some concrete space, a physical one as well as a temporal one. A flower, like a thought, a sentence, a book, is but a placeholder. Placeholder这个词不大常用，是数学中的有效零和占位符，是语言学中的占位成分，如形式主语或宾语。回答问题时她提到placeholder 的意义在于创造空间（make space），还说：my nonfiction is written to make space for my fiction.
