Question: I developed flu-like symptoms a few days ago and was tested positive for COVID-19. Naturally, this put our whole family on panic mode as they need to stay home and self-isolate for 14 days to see if they develop symptoms as well. I feel fine otherwise and try to keep positive, but I feel apologetic to my family as well. As I can’t go to the office now, how do I tell my Japanese boss that “I’m infected with the coronavirus” in Japanese?

Question: I feel lonely as I must stay home all the time during this period of self-restraint caused by COVID-19. I have been sending messages to many people. I want to send a message “How is it going?” to a Japanese girl whom I used to go out with. How shall I say it in Japanese?

Question: I have judo classes in America. My sensei is a Japanese. Unfortunately, the class is closing because he is going back to Japan. We would like to write him a thank-you card. How should I say “Thank you for your guidance” in Japanese?

Usually in a Japanese conversation, you do not have to spell out the whole sentence if the context is very clear to the speaker and listener. In your example, it is clear that your team would fall behind in the schedule if the other team does not deliver on time.

Question: 
Whenever I happen to see my elderly Japanese neighbour while leaving home, she would ask me where I'm going (dochirae?). Why is she so concerned about my whereabouts? I don't know how to reply her so I usually just smiled. How do I reply her?

Question: We had a Japanese visitor in our company today. When I introduced myself in Japanese, he was surprised and said that I was good at it (Nihongo ga joozudesune. 日本語が上手ですね。). I was a bit embarrassed as I could only manage simple greetings. Does he really mean it?
