Our mailing system for the teachers and the office workers (only) in the university was somewhat tied up. I worked all day without an e-mail, which was weird; I was nervous whether I miss some important information.
I was invited to give a talk for company managers and engineers in Shimosuwa, my hometown. I asked my parents if they wanted to come, but they hesitated. Anyway, I started working on the presentation, which requires no internet connection.
It will be a two-hour talk for non-specialists, my first experience in my life.
