What was the twist in this short story?

Context:
Matilda is woken up by the wind; she looks out the window; her neighbour, Marie, is fetching flowers from the garden and then Matilda’s mother is called for the telephone by Bogey, Matilda’s brother. Matilda is off to Mr Bullen's for her music lesson. Her mom does not want her to go due to the strong wind, but she goes anyway. After the lesson, she goes for a walk with her brother to the esplanade. Here, the story changes from present to past narrative as Mansfield shows that the music lesson, the walk etc. all occurred in Matilda's past, and she and her brother are actually sailing away on board a ship several years down the line, that all that went before were memories.<|im_end|>
