Mrs T can load the dishwasher so that it looks completely full even though it only contains half the number of items that I could fit in it.
It drives me nuts.
I appreciate that this is largely my problem rather than hers.
I was in the Cavalry in the service, mounted in M3 Bradleys. We didn't really have to do much improv packing, the interior of that beastie was very well planned, but the lessons stuck and I'm definitely very good at it. From garage shelves to suitcases I'm the man. But the first term I ever heard for that particular skill was "Tetris".
