I always did wonder what would happen if you answered honestly to this, because I also have my wife pack my bags and have accepted bags prepared by my sister without checking them. Also have left bags out of my sight at times.
In fact when I worked on cruise ships we used to take the crew bags from them the night before they disembarked on leave, and would open and inspect a selection of them for theft and they'd receive the bag again on clearing customs in the terminal before heading straight to the airport.
