My bedroom is my home away from home, so to speak. It’s the one part of the house that no one is allowed to barge into, they have to knock, and I have to tell them to come in. If I really want to be alone, no matter the reason, I lock the door, turn off all the lights, make sure the blinds are drawn (what I wouldn’t give for some blackout curtains, though), sit down on the floor or the bed, and just relax. Sometimes I do it just to listen to music for a while with no interruptions, not necessarily because I’m in a foul mood. It sounds simple, and maybe compared to other people’s oases it is, but it’s what works for me.
