Light be gone

Sunlight, street light, security light you are officially not allowed in my room unless I let you go. I have had a blackout blind fitted to my bedroom window's, after 2 years of blinds which are inside the window I have now got a proper covering. Which is not only thicker to keep the light out, it provides a covering when the windows are open. It's been fortunate my room is on the 2nd floor.
