The extract is taken from Virginia Woolf's novel Mrs Dalloway.
From the title the reader can expect the novel will be about a married woman.
The extract deals with a morning of Mrs Dalloway's life, and it is set on a morning of June in London during 1923, when she decides to go out  to buy the flowers for a party she is going to host that evening.
In her house there are the preparations for the party and even the doors must be perfectly clear. This makes the reader  understand that parties were very important social events in aristocratic environments in that period.
She notices it is a wonderful morning as if it is created for children to go to a beach. This makes the reader understand it is summer or spring.
From a sensory experience (the squeek of the door hinges ) Mrs. dalloway  goes with her mind to the past, when she was living in Bourton and  she was eighteen years old. This reminds her she used to open the bow window of her room and she looked at the landscape with happiness but also with a certain restlessness (it was as if she perceived the oncoming war).
The memory of that morning makes her remind also Peter Walsh, one of her lovers. He is characterized by his comic vein, because Mrs Dalloway thinks about his joke on that morning, his positive features (his smile) and his behaviour.

It is interesting she reminds a man of the past, even if she is now married to another man and this makes the reader expect he was a very important person in her life, like a lover or a friend.
Moreover there are some references to the society of the period: she was on a terrace, so she was an aristocratic woman. This is a reference to the behaviour of the upper class of the time.
Mrs Dalloway is also characterized by the point of view of another person, Scrope Pulvis, a neighbour. She is portrayed as a charmig woman around her fifties and he thinks also she is full of life even if she has been ill. So the reader can understand something about her look and her attitude.

The narration later goes back to Mrs Dalloway's point of view.  the shift makes the reader understand  her reflection is stirred by a sound: t this time is the toll of the Big Ben. It  makes her  feel suspended.  in her opinion. In her opinion everyone,loves life. There is also a description of London's life: while she is walking, she sees omnibuses, motorcars, sandwich men and people: this is the portrait of a living modern and busy city. But there are also poor and unhappy people, and she does not think they may not like life because of their condition. This is the typical point of view of an aristocratic person.

At the end she thinks she loves life, London and that moment: she seems satisfied with  her life.

The narrative technique used is the interior monologue: it allows the reader to follow Mrs Dalloway's mental associations and their effect on her. There is also the interior monologue of another character,  a short one but all the same it allows the reader to see Mrs. dalloway from an external perspective.

The characterization of Mrs Dalloway is built up with her surname (more important than the name in that society), her association, her feelings, her thoughts, her memories, her social status, her behaviour and by what she likes (to buy flowers, to give orders to servants and and organize parties).
The narrator is a third person omniscient narrator, (because he knows what she feels and thinks) but not intrusive.

The language used by the writer is more similar to the language of poetry than the language of novel. There are many similes in the text (air like a wave, the metaphor between Mrs Dalloway and a bird).
The reader has the feeling to be inside Mrs Dalloway's mind. In this way the writer makes the reader feel and see what Mrs Dalloway herself is feeling and seeing. Moreover the reader can understand the point of view of the world of an aristocratic woman at the beginning of the 20ieth century.
