It was my first dance and was so busy dancing that didn't pay attention to anything else. I didn't realize that I got too close to the rim of the stage. Suddenly, I tripped and fell of the stage. The music stopped for a while and everyone laughed, including the guy that I had crushed on. I felt so stupid. It was a dance party that I would never forget.
