In Episode 13, Haruhi is talking to Kyon after visiting the apartment
building formerly occupied by Asakura. Haruhi tells about the time her
family went to a baseball game. She was amazed at the sight of 50,000
people in one place. Later she calculated it to be only one
two-thousandth of the population of Japan, and a minute fraction of the
number of people in the world. Suddenly, she felt insignificant. She says:
"I had thought myself to be a special person up until that point. I
enjoyed being with my family and most of all I thought that my class in
my school had the most interesting people in the world. But that was
when I realized it wasn't like that.
"The things that happened in what I believed to be the most enjoyable
class in the world could be found happening in any school in Japan.
Everyone in Japan would find them to be ordinary occurrences.
Once I realized this, I suddenly found that my surroundings were
beginning to lose their color. Brush my teeth and go to sleep at night.
Wake up and eat breakfast in the morning. People do those everywhere.
When I realized that everyone did all these things on a daily basis,
everything started to feel so boring. And if there were so many people
in the world, there had to be someone living an interesting life that
wasn't ordinary. I was sure of it.
"Why wasn't that person me? That's all I could think about until I
graduated from elementary school. And in the process, I realized
something. Nothing fun will happen if you sit around waiting. So I
figured I would change myself in middle school. Let the world know that
I wasn't a girl content with sitting around and waiting. And I
conducted myself accoringly. But in the end nothing ever happened.
Before I knew it, I was in high school. I thought something would have
changed."
Of the information we are given, this seems to me to be the most likely
candidate for the triggering event. She felt insignificant, ordinary
and boring at the end of elementary school, so she decides to take a
proactive stand and change her attitude at the beginning of middle
school - three years before the story begins.
It could still be something else, but this is the only thing I've seen
that matches the time and could be the cause of a
world-changing/creating event.
