I see a door, except the door has long been broken, ever since we got the house around 15 years ago.
So it is to the side of the doorway, a useless piece of wood. A flag bearing random soviet symbols drapes across the entrance. Through the doorway is a long corridor ending in a wide open window. Through this window is a stunning view of Penzance. Closer to hand is... wait what the hell is that thing? I see a wooden box thing right next to my computer desk. It is not a box but some sort of very small, badly made alcove protruding from the wall, not indented in it. Why don't I notice it? Perhaps it has been there so long I forget about it, it is just part of the room. But I cannot think of what it's use is. It's interior is covered by a wooden door. What do I do?

pen the door
:leave door
I open the door to reveal the dusty innards. Cobwebs string across the box's interior. The only item inside is a plastic wall fitting. It loosely resembles a plug, but both the wall fitting and the plug are larger than normal, and blockier. They seem almost unable to be removed from each other. On one side of it is a large, visually unpleasant switch. I have no idea what it does. It looks like it is stuck a little, and it is covered with cobwebs, and I have a phobia to spiders. What should I do?
:Remove the cobwebs with random large police torch I keep lying around for some reason?
:Flip switch with police torch?
:Leave switch alone.
I flip the switch with the police torch, it requires effort, it is very old and large. Once the switch is flipped the room goes dark, the computer shuts down and I will need to write this response again. Balls. Also I still have no idea why there is this thing in my room anyway but I guess it is important somehow.
So there you have it, I am not sure why I turned it into a adventure game but I think I was just enjoying the sense of adventure. And I also don't know why I went through the trouble of re-typing it again. But anyway at least you got an interesting response, or at least for me it was, now I know what is in that random wall-box. A doom button. I wonder if I have other random things stuck on the walls on other parts of my house?
