This afternoon I got an email notifying me of the death of a classmate who studied together at our laboratory when we were university students. According to the email, last Sunday he suddenly had a stroke related to type I diabetes he had been suffered from, and passed away. He was as old as I.

It is my first time that I lose a classmate with whom I shared the same memories at school. It is surprising and regrettable.

I can't attend his funeral and say good-bye to him because the funeral hall is too far from where I live, but instead I sent a telegram of condolence with the other classmates and I'll keep his memory in mind for life.
