One day I was waiting for the bus as usually. When it comes, I just followed the other people and got on. I was listening to my music, but I didn't notice that the bus was going in the wrong of direction. Then I looked out of the window and everything seemed strangely to me. All of sudden, I realized I was on the wrong bus. We were in the middle of the countryside, so he couldn't get off(下车). The bus finally arrived back in the city center. Then I had to wait for the right bus. Unfortunate, it took me three hour to getting home instead of twenty minutes.
