Testing for COVID-19

My mom got a cold yesterday. Now, we are pretty sensitive about illnesses so I recommended going to see a doctor. She did a PCR test but she wasn’t positive. On the other hand, I worked hard as usual. I taught web design to my student. I was conscious about improving my teaching skill. In the evening, I went to a dentist to clean up my teeth because my teeth had a lot of dirty stains. It was only 2650 yen. I really appreciate the national insurance system. If I had this done in a foreign country, I would have had to pay more than 20,000 yen. I fell asleep at 10 p.m.
