That day, I remember, because that day was the 'first day' when I went out of the room (because I stayed in the room for a summer vacation and seldom communicated with the outside world). I even didn't know how to open the door of the room. Usually, my grandparents came in to deliver food and paper. The living room was so strange, and my eyes were pricked by the light that brought light to people. Turn around and have a look, it is full of black, and I have experienced insomnia, loneliness, tears My room has become so warm now. Open the curtains, open the windows, and let the pain go. I'm happy! No more pain! I'm full! Good sleep! This is the outside world!
