An Embarrassing Experience - Draft one

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 lock.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.Since then I have been very careful when I go to the rest room.
