nice job  neither me nor my wife lose our stuff all that often but when we do we rely on each other to bring in the out of the box thinking necessary sometimes theres an explosion of magic in our flat and a thing i need vanishes and i start to get annoyed trying to find it and then my wife comes and finds it in the very place i just checked twice but on the flip side ive developed a subconscious habit of always tracking where my wifes phone is because invariably every other day she starts looking for it in panic its on the fridge honey and if she loses something for good my analytical thinking comes to rescue - i do essentially the same pattern you describe except due to accumulated emotions we also end up having an argument in the middle of it systematically going over every inch of the room whether or not its physically possible for the lost thing to be there  also theres a phrase thats banned in our home ill put it here so it doesnt get lost because whenever one of us utters it that very thing is doomed to be lost very soon
