We all know the story of The Reason for the Season and how a manager was just fine at the beginning for the King of Kings.
You ever routinely vacuumed the carpets a 3000+ sq. ft. house?
It takes about an hour and 15 minutes if there's a lot of carpet. If not, ya still gotta mop the hardwoods, tile etc.
Personally, I only need about 20 sq. ft. to rest comfortably at any given time and not much more to eat or watch TV.
A nice big house is not a bad thing....it's the love of "I just gotta have one" that gets people upside down in life.
About the max I'd want is 2000. And that's only because 600 of it will be my home theater. :D
