An Embarrassing Experience - Draft two

There were many embarrassing experiences which happened on me.And the most embarrassing situation let me lose my face. That day, I wanted to go to Taipei with my cousin. Before I took the train, I felt very nervous, because it was the first time for me to take a train.Then I went to the toilet to calm my feeling down, and I found the door couldn’t be locked. I didn’t think that was a problem at that time.Then, a person opened my door. I shocked, and closed the door quickly. Suddenly, I felt very shy and wanted to run away from the place. I will be very careful whenever I go to the rest room.
