There was no streetlight and the night road was dark. Because it is a new moon, there was no figure of the moon in the night sky, and I could not see the light of the star because it was cloudy. On the way home from the neighboring town there was a tunnel. It's a short tunnel, but tonight it was long. No matter how much I keep walking, I did not go out. I thought it was strange. What's wrong? Suddenly, I remembered a bad story. In the midnight of the new moon, walking alone makes it impossible to get out of this tunnel forever. The students were doing such rumors at school. Then I also remembered another story. When you look back in the middle of the tunnel, the exit will disappear and you will not be able to leave there forever. This is a superstition that I heard when I was a child. It is a strange story, but I can not bring myself to laugh. The exit of the tunnel is not yet visible. It may not be possible to go out in retrospect. But I can not go out even if I go forward as it is. I wonder what I should do. While walking I thought desperately. No before, no after. The remaining method is ... "That's it!" I cried unintentionally and the voice echoed in the tunnel. Although it may fail, there is no choice but to do. "Right turn!" I dared to look straight to the side. Then there was a tunnel exit there.
