In many 'A Call to Arms' - type short stories, the main character is often someone who has a strong sense of justice or a deep - seated need to protect something. It could be a young person full of idealism who sees the wrongs in their society and decides to take action. There might also be an older, wiser character who provides guidance. And then there could be the 'ordinary' people who are initially hesitant but are eventually inspired by the lead character to join the call to arms. Without reading the specific story, it's all speculation, but these are common archetypes in such tales.
The main idea often revolves around a call for action or a struggle. It could be about a character or a group facing a situation that demands a response, like a fight against injustice or a battle for survival.
It's hard to say without reading it. But it could be Harry, Ron, and Hermione as they are often central in Harry Potter stories. They might be the ones answering the call to arms.
The main characters include Raina Petkoff. She is a young Bulgarian woman who has certain ideals about love and war at the start. Then there is Captain Bluntschli, a Swiss mercenary who has a more practical view of war. And also, there are Raina's parents, who represent the older generation and their views on society and family.
There might be a caller and a receiver as main characters. If it's a call to action, the receiver could be a hero - type character. For example, a detective who gets a call about a mysterious case. And the caller could be an informant or a victim. There could also be other characters like the detective's partner who helps him in answering the 'call' and solving the case.
Not having read 'a sick call short story', I can only guess. There might be a protagonist who is the one in need of care due to being sick. Then, there could be a supporting character like a doctor with his or her own backstory and motives for making the sick call. There may also be family members who play different roles, such as a worried mother or a stoic father, and their interactions with the sick character and the person making the call would form an important part of the story.
There's no way to tell without reading it. However, it might be a young person calling an older relative for advice. Or it could be two lovers having an important conversation. Another possibility is that it's a detective calling a suspect, which would make the story more of a mystery - type short story.
Since I'm not familiar with this short story, the main characters could be a businessperson making an important call for a deal and the person on the other end who has the power to accept or reject it. Or it could be two friends or lovers whose relationship is explored through the phone call.
I don't have enough information to say who the main characters are in 'the phone call short story' as I haven't read it. But usually in a story about a phone call, there could be a caller and a receiver as the main characters.
