furniture can be moved. do you not have a backyard or garage, or driveway? even if you cannot perfomr the kata as you would at 100% as far as power, speed, proper spaceing, etc. you can stil go through the basic patterns in minimal space. i'm ure your wife would unerstand if a piece of furniture is moved for an hour. mine does. Do you have a yard? I practice in my back yard and side yard whenever I get a chance.
