This is my first grade elementary school student,
It is a story that I experienced.
At school only children in gymnasium,
There was a rule that should not be entered.
But I entered with my friend.
I played for quite a while.
Then barefoot from the corridor,
I heard the sound of walking with petapeta.
When I think that the teacher came,
I came inside.
But I only went inside with sound,
There was no figure of a person.
The sound coming closer and closer,
I became frightened and quickly returned to the classroom.
I heard it from the gym,
Even though there was no one at night,
It seems that the child laughs.
