The happiest day of the summer vacation should be my birthday. That night, I spent an unforgettable night with my family. In the evening, we went to a high-end restaurant for a delicious dinner. Then we went to a cinema to watch a very wonderful movie. The next day, I went to the beach with my family. We built a small castle on the beach and played many interesting games. We also had a seafood feast and enjoyed the beautiful sea view. This day made me feel very happy because I spent a wonderful holiday with my family.
