It was a fantastic party I've had in my life. The party was held in the last summer in my school. Joining the party are: my class members, my teacher and me. During the party we talked, laughed, and took a lot of photos. The most interesting part in the party is dancing. That was the first time I had seen my teacher danced. That was amazing. The party was end but up to now I've remembered it clearly, so exciting and emotional.
