I need to have one cracked part of the window that's like open air, but the rest of the window is blacked out. Yeah. So, that's this. there's a small amount of like one window in the bedroom that is going to have open air and I can't black that out because I need air to come in. Yeah. And then everything else is blacked out. And then what also I do is I have to crack the bedroom door a little bit so that there's air flow to the rest of the house because you can't just have the air won't come in in the same way unless you have cross ventilation.
