School closure

My wife got an e-mail about my daughter’s school closure. It’s because a first grader at the school was infected with coronavirus. Because of that, the school was shut down. To be precise, my youngest daughter’s class was shut down. The student infected with COVID-19 is in the same class as my youngest daughter. My eldest daughter was close contact with her sister, so she also have to be absent from school. When she heard it, she cried because she will graduate from school this month and there are a few school days left for her.
