It was fine and hot.
I took a half day off to attend the seminar of CEO in Kudanshita. It cost yen 1000. He spoke very fast but interesting.
After that I went to eat out with friends. I met three of them for the first time, but it was fun. I knew about the card reading called Kamioueki (神応易) for the first time there.
At night I went to Ikebukuro to attend the monthly meeting for the first time. It cost yen 500. There were five speakers there. I heard about very interesting experiences.
I was lucky to be able to get the last train.
