It's happened to everyone.
I'm sure it's happened to you.
The siduation is so simple and so ridiculously easy to get into, that even I would know.
It happens when our minds are somewhere else, too busy on other problems to take note of minor actions.
it happens when we least expect it.
It can drive us to waste hours of our time for NOTHING.
Most of all, It teaches us something; To take note of what we do and keep our minds on a wide focus, to mind everything we do. To Keep our heads clean and non-cluttered, if we can. This all adds up to fulfilled time and a chance to not get embarrassed.
So, what is it?
In short, It's a flash of deja vu.
Let me put it this way:
Have you ever been working, focused immensely or not on something...something sucking up your time, when suddenly you stumble upon the need to use your pencil and when you turn, It's not there. You refuse to retreat and go find another pencil. You've got to find the one you were using, and win a victory over the deja vu. So you stalk the house; you look in all the places you've been in the last hour that you can remember. You check all the possible places it could have fallen that the laws of phisics would allow.
Finally it comes to the defeated admitting that you've got to ask someone. Mom is the usual choice. And when you confront her, you are hopeful but don't really expect any useful information.
"Mom, have you seen my pencil?"
"Well, isn't it the one you're holding?"
And there's the pencil. Sitting in your curled fingers. Somehow it has managed to hang on without your brain knowing. But somewhere deep in your subconciousness some part of you had known there was something there that ought to be held on to. Your fingers were numb. You never even knew. That's at least how I explain deja vu.
"Oh. Yeah. That's the one. Thanks, mom."
And so you hastily slip out of the room. Half an hour of work wasted. On finding a pencil. At least it had been with you all along and not lost forever in a dusty corner of the house. Well, now you know where your lost pencils go. Some of them. And like most experiences in life, small or big, humiliating or just plain bad, we learn from them.
In this case:
Keep more alert and keep track of your pencils .
I'm sure this sounds familiar.
