“My problem is different. I live in a large apt building, and many of my young Frum neighbors think the hallway is their rec room.
They let the kids play out there all day.”
The Goq is correct. A hallway is just that; a hallway. It’s not a playground, where children can run around and make noise.
If the children want to play; then let them play in their own homes, or else let them go to a playground.
