Hmm. I was sitting at the desk, having quietly brewed a cup of black coffee. I tapped the desk lightly, lost in thought for a moment. Why am I waiting for a letter that never receives a reply? Such behavior is highly irrational. ... It must be because a belief still exists in a corner of my heart that a reply will eventually come.

... ... During my adolescence, the fact that you did not reply was a source of resentment. It would have been stranger not to feel resentment. When I was even younger, my faith that a reply would come was much stronger. There was even a time like that. I heard that it does not snow where you went, so I once tried to mail you some snow. I do not know if you still remember. It was a very irrational action. Even if the paper became damp and soaked, ... perhaps I wanted to send even the scent contained within the letter.

Though no reply ever came, the letters were never returned, so I could at least confirm you were alive. I was curious why my sister, who was always kind to me, would not reply, but... ... that, too, is merely irrational.
