OK. Is this the vent where you are doing Radon ventilation? Because if she's talking to the vent she's gonna need some help. We are talking Atomic # 86. She could be breathing cancer. And instead you took a photo.
I'm pretty sure that's a Jersey Radon vent. She's sucking up poison. First off. That's a door. Not a window. And it's been blocked because?Reasons. Most basements in NJ have Radon problems and have emission regulations. These involve useless fans and a flue. It's like having to pay for an Avrile Lavigne concert when you just want to see Billy Joel.
You are correct and if you look at the photo, somebody cut it off and the little girl is breathing radiation. Or maybe she's just talking to the laundry.
Oh and here is your Billy Joel.
