Lost in Plain Sight

Paula thought she had an important document in the entrance hall. It wasn’t there. She then thought she had moved it to a secure place, but could not remember where this would be. A little later, Totte pointed out that some documents of the kind lied on the kitchen table. It turned out that the important document was there, in plain sight. Well, I have also lost important things which I have later found lying around in plain sight. I wonder if the item can really be lost this way.
