One possible theme could be perseverance. If the characters are facing this never - ending rain, they might have to keep going despite the difficult situation.
I haven't actually read this short story specifically. But generally, a story with such a title might be about a day where the rain is a central element. It could symbolize a sense of melancholy or change. Maybe the rain is a metaphor for the characters' emotions that seem to go on and on, just like the rain that never stops in the story.
I'm not sure specifically as there could be various fictional or even some very strange real - life accounts with such a title. It might be about a day where there was an abnormal infestation of cockroaches that seemed like they were 'raining' down, perhaps from a building being fumigated or some other strange event that made it seem that way.
It could be a very imaginative and whimsical story. Maybe it's about a day when hearts literally rained down from the sky, perhaps as a symbol of love or some kind of magical event in a fictional world.
It's hard to say. It could be based on a real - life event that has been exaggerated over time. There might have been a situation where there was a large number of cockroaches in one area at once, and through the retelling, it became 'raining cockroaches'. But it also could be completely fictional, made up to shock or amuse people.
A possible theme could be 'unconditional love'. For example, a story about a mother who loves her child despite the child's mistakes. The child realizes this on Mother's Day and tries to show their love in return, maybe by doing all the household chores for the day.
One possible theme could be transformation. Since the title mentions 'the day everything changed', it likely focuses on how things or people are transformed in a short period of time.
The theme might be that of hope. In a world where there can be a lot of difficulties and uncertainties, a 'one lucky day' can give hope. If the story is about a person who has been down on their luck for a while, this one lucky day shows that there is always a chance for things to turn around. It could also be about the power of positive thinking. Maybe the character was in a positive frame of mind that day, which attracted all the lucky events, thus emphasizing that our attitude can influence our experiences.
Another possible theme is survival. If the story is set in a dangerous situation where a bullet is involved, the characters might be struggling to survive. For example, they could be in a war - like scenario or a criminal encounter where the presence of a bullet means life or death.
I'm not sure since I don't know the exact story, but it could be a young girl or boy who discovers the raining hearts and is changed by the experience.
A great theme could be 'Breaking Barriers'. For example, a story about a woman who is the first in her family to go to college against all odds. She faces financial difficulties and family opposition but still pursues her dreams. On Women's Day, she could be an inspiration to all women that they can break through any barriers in their lives.
