Walk from your right, and reach the middle.

You'll see that I'm standing there, having already arrived from the left, with a blueprint of a wall.
Let's build a ghost wall around us, with bricks, cements and no questions.

Let's stay for a while, and enjoy the warmth.
Remember, the wall can be broken anytime?

Because when we leave the round circle of middleness, suddenly the left and rights will seem much closer.
