（ 2） Dear Mr. Wayne,       I don’t know what to do, so I write a letter to you. Myparents and I went to Japan last month. We didn’t know aboutthe COVID-19 when we set off. It was not so serious then.However, when we came back, we needed to stay at home for 14days. We couldn’t go anywhere. At first, I was a little happybecause I didn’t need to go to school. I could play computergames every day at home. However, staying home was not thateasy. Both of my parents needed to work and they were seldomhome before. Now they start fighting about everything. Theyshout at each other almost every day just because of some littlethings. I am afraid of staying at home. I don’t know what to do.Please help me!Sad,Gary What to do 如何做
