Let's say you have something you need to take care of that requires a specific item. You know you brought that item with you to work, but can't remember where you put it. And so you root through your purse and coat pockets, and then Eureka! there it is. And even better, it's in there with another thing that you thought was missing. So, two things in your coat pocket. One thing you need, another thing you thought you'd have to replace. Now, which item do you carry with you most of the way to your destination? Who guessed the 'missing' item? Dude, your brain works just like mine. Which is to say, not well. If at all.
