The backpacker.
Sorry people, I’m the fool who clamps on the escalator. The fact is that I rarely ride the subway, 1-2 times a month, when you need to go to another office. On the way, I listen to audio books, often think hard and go on the autopilot. Therefore, in the crowd tightly supporting from behind, when entering the escalator, I involuntarily become immediately behind the man going in front of me, to the next step. When I realize this, there is nowhere to step back. I am ashamed, so forgive me and don’t be angry, I’m not of evil.
