The incident occurred at the time of junior high school students.
It was all the beginning that I caught a cold and was absent from school trip.
The day the cold has recovered, I went to school.
One of my classmates (A, hereafter) spoke to me.
"Hey, were you getting out with a tired trip?"
Listen to it, eh? I thought.
Because I am not going on a trip.
I "I have not gone on a trip,"
A "What are you saying, I was running around so much happily?"
Such a talk did not mesh at all in this feeling.
But this was not the only strange thing.
A few days later on the morning of one day, I went to school as usual and entered the classroom.
I "Good morning ~"
Then, everyone looked at me looking funny.
When I asked what happened, I said "I entered the classroom earlier, saying good morning."
I remembered what happened when I was on a school trip.
It's as if he / she has another person.
Now that I became an adult, that kind of thing has disappeared, is that a doppelganger?
