A letter to the high school girl who walked while saying, "Ah, this is so damn tiring."

This is a 100% true story that happened in Seomyeon, Busan.
A high school girl was walking in Busan and looking exhausted. Then suddenly, she walked while saying, "Ah, fuck, this is so damn tiring," right?
To that high school girl: That is actually a psychological warfare technique.
It's really hard while walking, isn't it? She has endured that for 12 years.
In fact, even someone weighing 100kg would be knocked out immediately if they were hit by that.
Is that high school girl serving a life sentence? Just because someone is serving life doesn't mean they are unconditionally using psychological warfare techniques.
If you keep being subjected to that, you actually develop schizophrenia. Even Special Forces or Navy UDT members would become complete wrecks if they endured that for just 3 years.
I bet some doctor, after experiencing it once, shouted, "How on earth are you enduring this?" I saw the doctor's eyes go completely blank.
That high school girl must have reflected on her actions a lot.^^
There must be a sane guy in Busan who was shouting, right?
