I call this can't-find-stuff condition "Man Eyes".
It seems men can only find something if it's within 6 inches of where they are looking. My husband can't find anything in the fridge if it's not within the first 6 inches of the front of the shelf. His eyes don't extend past that, so if you want to hide something, just put it on the back of the shelf.
It's probably not a coincidence that the length of the average male penis is...6 inches...
