Okay kiddo, so sometimes when people do something bad, they have to go to a special place called prison. It's like a big building where they have to stay for a while, kind of like a time out.
Now, sometimes when people are in prison for a long time, they can start to feel really sad and lonely. So, the people who run the prison might let them go home to visit their family for a short time, and that's called a furlough.
It's like a special permission slip that says they're allowed to leave prison for a little bit, but they have to promise to come back when they're done. Think of it like a break from jail, but only for very good behavior.
Does that make sense, champ?
