I'm not sure exactly as I haven't read it in full, but perhaps there is a character who takes care of the geraniums and whose emotions are reflected in the state of the plants.
One possible theme could be melancholy or sadness, as indicated by the'sad geraniums' in the title. Another might be the exploration of ordinary life and the small, often overlooked, events and emotions within it.
Henry is the central character in 'The Sad Story of Henry and Other Stories'. He is the one whose story is the focus. There could be other important characters such as his parents if the story delves into his family background. His friends might also be important if they play a role in his sad story, for example, if they abandon him or support him during difficult times. Additionally, there may be a love interest in the story who could have a significant impact on Henry's emotions and actions.
Often, young apprentices can be main characters in sad warrior cat stories. For example, an apprentice like Firepaw in some stories. He faces many hardships and losses during his journey to become a warrior.
Marilyn Monroe is a key figure. Her story is full of sadness. She was used by the Hollywood system and had a hard time in her personal relationships. Then there's Charlie Chaplin. He had his own set of problems, including issues with the authorities over his political views which led to him being exiled from the US at one point.
In 'Atonement', the main characters are Cecilia and Robbie. Their relationship is torn apart by a false accusation, and they endure years of separation and hardship.
Since it's 'The Monster and Other Stories', there may be a group of adventurers as main characters. They might be on a quest that leads them to encounter the monster. Each of them could have different personalities and skills. For instance, one could be strong and fearless, while another is intelligent and good at solving puzzles. And of course, the monster itself could also be considered a main character in a way, as it drives the action and conflict in the stories.
I'm not sure as I haven't read the specific 'neighbors and other stories'. It could be the neighbors themselves, perhaps an old couple next door, a young family, or a single person living alone.
Given the title, it's likely that the main characters are the 'other women'. These could be women from different walks of life, each with their own story to tell. There may also be other supporting characters like friends or family members who influence or are affected by the situations these other women are in.
Without having read the 'Longing and Other Stories', we can only guess. Maybe there are characters like a young person full of dreams and longings, a middle - aged person who has lost their way in life and is longing for a fresh start, and an older character who looks back on their life with a sense of longing for the past. These are just possible character types that could be in the stories.
Without having read the book, it's difficult to determine the main characters precisely. But it's possible that there are characters from diverse backgrounds. For example, there could be a working - class character who dreams of financial freedom, and a creative character who desires artistic freedom. These different characters would then interact and their stories would unfold in relation to the overarching concept of freedom.
