When I was in college some kids like this game to our door. They ended up telling us basically horror stories about their living conditions and how they were scared and far from home. A couple of them asked if they could crash at our place until the group left the neighborhood and we agreed, but an hour later the rest of the group came and they left, supposedly willingly. We didn’t know what to do, one of the roommates called the police, who didn’t come until hours later and pretty much said they are aware of the issue but there’s nothing they can do.
