Curtain

Okay kiddo, so a curtain is like a big piece of special fabric that you can hang up in front of a window or doorway. It helps to keep bright light out of the room when you want to take a nap or watch a movie. It also gives you privacy because people outside can't see inside when the curtain is closed. You can open and close the curtain like a big door by pulling it to one side or the other. Some curtains also come in different colors and patterns so you can pick ones that match your room.
