As I was coming home from work today, I was riding the train, and I saw a moth. It was a tiny moth. It seemed that no one else was watching the moth, but I was. It flew around aimlessly, seeming to be lost in the train car. I went back to reading some news on my phone, then I saw the moth falling from the ceiling of the train. It was motionless on the floor for 2 or 3 minutes, then started moving. I wondered if it was blown down by the air conditioner. It moved a bit, but something was wrong. It was on its back. Eventually, it righted itself, and started walking around on the floor. Finally, it flew around again, probably having completely forgotten what happened. Then I lost the moth, and couldn’t find it again.
