Is that so Difficult word? “Isogashii” means “Busy”

Today is the thirty-eighth day of the spring semester 2024. Since today is Thursday, I have three classes to teach, although I feel even one class is enough to make me exhausted these days. One teacher (of this country) asked me to introduce some literature about tense and aspect of Japanese. I don’t have any literature of research level about such linguistic issues. This morning, I made a photocopy from a book that I have. And I brought it to his office in lunch break. Since he wasn’t there, I passed my photocopy to other teacher who shared the office.

After two classes in the afternoon, I got back my room. And then I slept half an hour on my bed. Though it already turned to be dark outside, I went to the campus super market to buy some food. I met two male students there. They were the third-year students. I had taught them when they were the second-year students. I asked them in Japanese “Isogashii desuka?” It meant like “Are you guys busy these days?” To my surprise, they didn’t understand what I asked. The adjective “Isogashii” is a word to learn during the first year. It seemed as if they had already forgot Japanese. I felt it difficult to continue to communicate them, so I said good-bye to them. It looked like they were still talking each other about what the word “isogashii” was. It was a funny moment.
