You walk into the living room, the area where the family will spend most of their time gathered together. Several comfortable looking chairs and a couch arc before the massive flatscreen tv hanging from the wall, and pictures of each family member, alone or in groups, speckle the walls.
From this area, supplies will be plentiful, and there'll even be a little entertainment available when the Andersons gather to watch a program. With such a vast amount of traffic however, there is the increased risk of being spotted, or just plain accidently crushed underfoot. But you wouldn't have opted for such a survivalist lifestyle if you feared taking risks!
So, where would be the best place to station yourself? Still regular size, you check the room thoroughly before you take the plunge to an eighth of an inch. You want to get this right.
Under the couch, right up against the skirting board, you will be out of sight. Bar any decisions to move the furniture to vacuum underneath, no one will spot you. You run a hand along the carpet underneath the couch, and find it pretty clean; it must have been done recently, so you have some time before you'd have to fear being sucked away. Time to prepare.
The device is simplicity to use, and in moments you are a speck, traipsing under the impossible awning of the couch where before you could barely squeeze your arm underneath. You marvel in the sheer scope and scale of your new home.
The skirting board sounds solid to a cursory rap of your knuckles, but at this closer scale you can see how fragile it is, how easy it would be for you to dig in, termite-like, to construct a living area for yourself in the very fabric of the room. You hadn't considered it before, but it's something worth contemplating. It would be more tiring than simply setting up your little tent, but may be worthwhile in the end.
And there's always the third option: go without. Why tie yourself down? There's no hostile climate to fear indoors, and leaving evidence of your dwelling is just more likely to lead to discovery, whether you're present there or not. Perhaps it would be better to live as a nomad within this room, without any ties to a specific point, going where the food is and living beneath chair or couch as the mood takes you.
Where the mood takes you... Looking upward, you see the vast expanse of the ceiling. It may be crazy to think this, but then it's surely crazy to shrink yourself this small in the first place. Why not live up high, and swoop down when supplies are needed? Live like a spider, some crazy series of ropes and pulleys...
No, no, surely that's a step too far... But some height might be helpful in avoiding the feet of the family. Maybe it would be possible to scale and nest within a bookshelf...
