Why does nick go outside in the rain during tea?

In F. Scott Fitzgerald's "The Great Gatsby," Nick goes outside in the rain during tea as a moment of reflection and emotional release. The rain symbolizes his internal turmoil and the chaotic events surrounding him, particularly regarding Gatsby and Daisy. Stepping outside allows Nick to momentarily escape the tension and the complexities of the social interactions happening indoors. This act emphasizes his role as an observer and highlights his growing disillusionment with the world around him.
