Once a week I had to visit the General Staff of the MO at the 1st Frunzenskaya.
The road went through a small square adjacent to the fence of the General Staff.
And then one day a fence appeared around the square, where it was a meter high,
Now to get to the General Staff, it was necessary to run around the square almost in a circle.
And I go again, and the section of the fence is so carefully cut and stands in a row, the road is free.
Next week, the road is closed.
Another week, I go to the section in general cleaned the road open
A week later, the new section of the road is closed.
Another week above the section built a transitional staircase like through a pipeline
On the other side of the road, the road is open.
Another week and I see that the staircase is inside the fence and the road is closed.
It became interesting what will happen next.
Not a week has passed, I go, the staircase stands again through the fence and is deadly attached to it on both sides.

I don’t know what happened, I wasn’t there anymore.
But I know for sure: in MO it could last a long time.
