Объяснение:

Yesterday I had an extremely unsual day. Unfortunately, I forgot to turn on my alarm clock and that`s why I went late to school. When I finally came to my school, I tried to open the main door, but in was closed. Then I saw the paper sticked to the wall. I tried to squint and look at the writing on paper. It said:"School is closed for quarantine". I was a bit disappointed. I did not know what I should do next. Anyway, I decided to go home. I was bored, so I called my friend, she started to laugh at me. I did not understand why. But then she told me that it was Sunday.
