On the first day... a man walks down a street...
Suddenly the world goes dark. He thinks he is lost.
Then he realizes he is in a deep hole. He tries to find his way out, and it takes a very long time. Once he is out the day is gone ... so he walks back home.
On the second day... the man walks down the same street.
The world goes dark again. He is in the hole again.
He takes a while to recognize where he is.
Eventually he finds his way out... and so again he walks back home.
On the third day... the man again walks down the street.
He knows the hole is there and pretends not to see the hole... and closes his eyes. Once again he falls into the hole, and climbs out ... and walks back home, the day lost once again.
On the fourth day... the man walks cautiously down the street.
He sees the hole and this time walks around it. He is pleased.
But the world goes dark again. He has fallen into another hole.
He climbs out of the second hole, walks home ... and alas... falls into the first hole. He gets out of the first hole... and walks back home... to think.
On the fifth day... the man walks confidently down the street.
He sees the first hole..... and recognizes it.
He walks around it... but forgets the second hole, which he walks directly into.
He gets out immediately... and walks straight back home - to weep and hope.
On the sixth day... the man walks nervously down the street...
The hole is there and he thinks "I won't fall into the hole again"... and walks around the hole. He sees the second hole, avoids the second hole... but as he passes, he loses his balance... and falls in. Climbing out he walks back home ... taking the time to carefully avoid all the holes.
On the seventh day... the same man goes for a walk....
... and chooses to walk down a different street.
