I don't even have to do that and there is a dog here.? They just open the sliding glass back door and let her come and go as she pleases.? It stays open even when they have the air on.? Last night when she went to bed I told her the windows upstairs in the kids' rooms were open and she said it will be fine and turned the air on anyway.? When I went to bed a few hours later the air was on and running?and the windows were still open.? See what I mean by stressing me out more??
