On the day of the farewell banquet, I propose a toast to all the teachers who came to the meeting and thank them. Seeing off a respected teacher, he walked out of the hotel and bowed. In the last few days of school cleaning, I left the dormitory one by one. I accompanied them to the door of the dormitory, stood at the door and said with a smile that I should pay attention to safety. Seeing my roommate disappear on the stairs, I quickly turned to close the door, turned on the computer and played games seriously. I ordered takeout in the evening and continued to play after eating. On the last day, I sorted out books, kept a few books I had read, a camp card for freshman military training, a school card given by my roommate and a graduation photo, and mailed them home.
