Once I was in the restroom of a railway terminal. It was what some people would call "no.2". As I was sitting there, I noticed that there was a footstep outside. Incredibly, an eye looked into my private space through the keyhole. It was a small boy, about 5 years old.
The boy looked into the toilet quite eagerly. His eye showed all the symptoms of earnestness and concentration. Naturally I felt strange, but then understood.
The boy apparently wanted to go to the toilet so desperately. An emergency situation. It was apparently "no.2". If it had been "no.1", the boy would have gone the other way. As the boy was so intent on going to the toilet, he was looking into the otherwise private space, to see who was there, and what he was up to.
Fortunately for the boy, I was just about to finish. So I said, "wait, I will be finished very soon. Just wait!"
After flushing, I opened the door. A cute boy hurried into the toilet, noticeably relieved.
As I went back to the corridors of the terminal building, I could not help smiling. How desperate the boy must have been! To this day, I remember the very intent expression of the boy's eye in the keyhole. It reminded me of a wild rabbit I once encountered out there in Scotland.
