6月に北大、北海道科学大、室蘭工大にレクチャー、集中講義に行く。飛行機やら、ホテルの手配してたら半日潰れた。なかなか時間感覚が掴めず慣れた外国行くより不安。In June, I will be giving lectures and intensive lectures to Hokkaido University, Hokkaido University of Science and Technology, and Muroran Institute of Technology. I was arranging for an airplane and a hotel and I spent half a day. I can't get a sense of time and feel anxious, almost more worried than going abroad.
