When he was leaving the laboratory, he said to us "I'm going to date・・・"
Because today is the day females in Japan are supposed to present chocolate to their sweetheart, he was expected to get chocolate from his sweetheart in the evening. On the other hand, I got no chocolate today including what is called "Giri chocolate", which is the chocolate given by female acquaintances formally.
Long ago, a female who lived near my home gave me chocolate on February 14. But, she stopped giving me chocolate when I was a junior high school student. Its reason is still unclear.
