Around 1:50, most of the students returned to class, headed to their lockers, or went to the gym to practice, as they had heard. There were empty chairs left and about four people sitting alone eating or working. Around 2 p.m., for about 10 minutes, the living room was completely empty. Chairs were scattered and sofas moved. 2:25 p.m., a cleaning lady came by. She cleans and places the sofas in the exact order they were before. 4 single sofas lined up against a table near the wall, four large navy blue sofas against each other in the center and 3 sofas against the escalator
