Blinds. And I close them.
Depends on the season. In the summer I sleep with curtains open so i can rise with the sun. In the winter I sleep with curtains closed because I leave my christmas lights on all season and they are bright.
Whatever position it was in when I entered the room. Except in summer because it doesn’t get dark enough in summer.
MY bedroom windows face the main road and its very large, would be quite the show, so closed
Always open because I have none.
