The main characters might be those who have a dangerous profession like deep - sea fishermen. They face the perils of the ocean on a daily basis, with storms, equipment failures, and the unpredictability of the sea. Their stories of how they manage to keep their lives on the line while making a living could be what the 'life on the line real story' is all about.
I don't have enough information to know who the main characters are. It could be ordinary people who find themselves in extraordinary and life - threatening situations, like a hiker lost in the mountains and having to survive against all odds.
I'm not sure specifically without more context. But often in such a story, there could be a hero or heroine who is facing a difficult situation and trying to survive.
Since I haven't read the story, I can't say for sure who the main characters are.
The main characters could be those who are directly involved in the situation where their lives are on the line. For instance, if it's a story about a sinking ship, the captain, the crew members, and the passengers could be the main characters. They each play a role in the struggle for survival, with different levels of knowledge, skills, and courage that contribute to the overall story.
The main characters in the 'life line short story' might be people who are facing some sort of crisis. It could be a doctor and a patient if the story is about a medical emergency where the doctor's actions are the patient's 'life line'. Or it could be a teacher and a student if the story is about how the teacher's guidance is the student's 'life line' in academic or personal growth.
Since I don't know the exact 'life in the line true story', it's difficult to say who the main characters are. It could be the workers themselves if it's a story about a high - risk job like working on power lines. They would be the ones facing the challenges and making the story interesting.
Since it's a true story, the main characters are likely to be real people. They could be ordinary individuals who find themselves in extraordinary circumstances. Maybe it's a worker in a high - risk profession, and his coworkers and supervisors are also important characters as they are all part of the environment where the 'life on the line' situation occurs. It could also include people who are helping or hindering the main character's journey, such as medical professionals if the story involves a health crisis, or community leaders if it's a story about a community - wide problem.
I'm not sure as the title doesn't give that away. It could be ordinary people who find themselves in extraordinary circumstances.
Since I don't know the specific story, it could be the person whose life is at risk. Maybe it's a single individual like a fisherman lost at sea trying to survive.
Since I don't know the exact 'Mending the Line' story, it's hard to say. But if it's a fishing - related story, the main character could be a fisherman.
I'm not entirely sure without reading the story specifically, but there could be a protagonist who is directly affected by being on the colour line. There might also be family members like a mother or father who play important roles in how the main character copes with their situation.
