Hmm. He sat at his desk, having quietly brewed a cup of black coffee. He tapped the desk, lost in thought for a moment. He wondered why he was waiting for a letter that never received a reply. Such behavior was highly irrational. ... Perhaps it was because a belief that a reply would eventually come still existed in a corner of his heart.

... ... During my adolescence, I resented the fact that you did not send a reply. In fact, it would have been stranger not to feel resentment. When I was even younger, my belief that a reply would come was much stronger. There were times like that. I once heard it did not snow where you went, so I tried to send snow inside a letter. I do not know if you remember that now. It was a very irrational action. Even if the paper became damp and soaked, ... I suppose I wanted to send at least the scent contained within that letter.

A reply never came, but since the letters were never returned, I could at least confirm you were alive. I wondered why my sister, who was so kind to me, would not reply, but ... ... this, too, is merely irrational.
