I'm not sure specifically which 'homeless man and couple story' you're referring to. It could be about a homeless man having an encounter with a couple, like they might help him, or there could be some sort of conflict or an interesting relationship development among them.
The homeless man couple might have a story full of hardships. They could be struggling to find shelter, food, and basic necessities every day. Maybe they met on the streets and formed a bond out of their shared situation. They probably face a lot of challenges from the weather, lack of proper healthcare, and social stigma.
Well, in this true story, the couple could have been going about their daily routine when they noticed the homeless man. They decided to stop and help. They might have given him money for food or even invited him to have a meal with them. They could also have talked to him to understand his situation better and tried to find a way to get him off the streets, like helping him look for a job or a place to stay.
Once upon a time, there was a homeless man and woman. They met at a shelter. They had nothing but each other. They would search for food together in the trash cans behind restaurants. They made a little 'home' in an abandoned building. Every day, they shared their hopes and dreams. One day, they found a lottery ticket on the street. They used their last bit of money to check it. And it turned out to be a winning ticket. They got enough money to get a small apartment and start a new life.
One consequence could be that they lose the trust of people who might have otherwise helped them. If their story is found out to be false, those who were giving them support may feel betrayed and stop helping not only them but also other homeless people.
I'm not sure specifically which 'homeless man and couple made up story' you're referring to. There could be many such stories. It might be a story where a homeless man and a couple get involved in some sort of fabricated situation, perhaps for personal gain, like faking an accident to get compensation.
One possible story could be that a couple, feeling generous, decided to help a homeless man. They bought him a warm meal and some new clothes. The homeless man was so touched that he shared his life story with them, about how he lost his job and family. This encounter made the couple realize how lucky they were and they continued to support the homeless man in getting back on his feet.
