At the end of the drinking session, some tributes and flowers were presented to me. And, this was the first time I met a new employee assigned to my previous workplace.
The problem happened during the second drinking session. Because I forgot the exact time of the last train to my nearest station, I had to walk all the way from the station where another train was available to my home. It took me 170 minutes to my home.
It is ironical that I didn't remember the exact timetable, in spite of the fact that I'm a railfan.
