In my case: Our furniture gets used, bumped into by the vacuum (luckily it's solid teak and pretty hard) , but
SHE knows enough to respect MY speakers. They don't ever move and are in the same condition as when they were installed.
I've also included her when going to purchase furniture or speakers and she's well aware that the speakers were more expensive (by a little) than the handmade Asian teak/marble/mother of pearl set. Having her there on the buying experience makes her an accomplice and now has emotionally invested in the purchases too.
