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 tyep I diabetes he had suffered from, and passed away. He was as old as I.

It is the first time I have lost a classmate with whom I shared the same memories at school. It is surprising and regrettable.

I can’t attend his funeral and say goodbye to him because the funeral hall is too far from where I live, but instead, I sent a telegram of condolence, and I’ll keep his memory in mind for life.
