Woolf shows us the living conditions of the British upper class through Mrs. Dalloway's life on a day and her flow of consciousness. Mrs. Dalloway's banquet is like the showroom of all kinds of people from the upper class. They compete to show their so-called magnificence, knowledge, and try to hide their “weakness”. Woolf successfully uses the technique of stream of consciousness, across the boundaries of time and space, shows the life of the person's psychological time in a day of physical time, thus making the life experience of Mrs. Dalloway and that of Septimius into the same river of consciousness. At the beginning of the novel, Mrs. Dalloway said she wanted to buy flowers herself. The author comes straight to the point and brings the reader into the spiritual world of the characters. It describes a wonderful flow of consciousness when Mrs. Dalloway left home and wandered alone on the streets of London.
