1/28（Fri）
I had an online English lesson in the morning. Ms. Colette told me the conversation partner at Cambridge public library and Japan Boston festival.
Then, I went to a barbershop, grocery store and had a booster shot at the CVS store.
1/29 (Sat)
Nor’ Easter. Heavy snow all day.
I had pain in my left hand. However, after taking Advil, I didn’t feel terrible.
I could read literature about the Lisbon earthquake and took some memos.
1/30（Sun)
I organized memos that I made yesterday and wrote a manuscript about it. I finished writing the Lisbon earthquake history from my perspective. It was about eight pages. I think that today’s description was OK. I realized that I should write a manuscript just after reading it.
I was unexpectedly able to write about optimism. The discussion between Voltaire and Rousseau was about optimism. I realized that it was one of the main issues in the disaster and civilization.
