my room: ~112 square feet on a wall to wall basis, but effectively 100 square feet due to the design cutting down on the *habitable* volume of the room
my free space: 4 square feet of open carpet
I.e. my room is basically a square, but when you take in to account what passes as furniture and all of the crap I'm stuck living with; that gives me a 4 1/2 by 6 1/2 foot area, whenever I am not sitting on the bed.
Last night I was watching a movie called Carbine Williams, about the genius; after looking at the scenes of the "hole" he was thrown in, really made me glad that I at least get to stretch my legs. Unfortunately, my life at home is just as good as dead, for all practical intentions...
