One could tie up all the loose ends in the plot. For example, if there are unresolved relationships between characters, they should be sorted out. It might also be a good time to bring in a final climax or revelation to make the story more impactful.
I'm not sure as I haven't read the actual 'Before the End of Summer' short story. But generally, the main characters could be a young person, perhaps a teenager, who is experiencing the end of summer and all the emotions that come with it. It could be someone who is about to leave for college or start a new chapter in life.
Typically in a story titled 'before the end of summer', the main characters could be young people. For instance, it might be a teenage protagonist who is about to enter a new phase in life as summer ends, like starting high school or college. There could also be friends or family members who play important roles in their life, such as a best friend with whom they share all their summer adventures, or a family member who gives them advice or causes some conflict during this time.
Another theme might be change. As summer is coming to an end, things are about to change. It could be about a character's transition from one phase of life to another, like going from the carefree days of summer to a more serious part of life such as starting a new school or job.
Use music or sounds in the story if possible. If it's a story set in a party, describe the upbeat music and the laughter of people. Or if it's a more quiet scene, the sound of cicadas at night can add to the mood. As the end approaches, these sounds can either fade away or reach a crescendo, depending on the desired effect.
One possible theme could be the passage of time. Summer is a time often associated with freedom and growth, and the idea of 'before the end' might imply a sense of urgency or change coming. Another theme could be lost love. Maybe there are relationships that are about to end as summer comes to a close. It could also be about self - discovery. The end of summer can mark a transition period where a character realizes something new about themselves.
There could be many different stories with the title 'before the end of summer'. It might be about the events, relationships, or personal growth that occur during the last days of summer. For example, it could be about a group of friends having a final adventure before they all go their separate ways when summer ends, with themes of friendship, nostalgia, and the passing of time.
I'm not sure as I haven't read it specifically, but it might be about the passage of time, the significance of summer, or personal growth during that period.
One book that might be similar is 'Atonement' by Ian McEwan. It has a complex narrative with themes of love, regret, and the passage of time much like stories set during a particular season.
