“Here we are at the beach! Watch the fluffy clouds in the sky and listen to the sound of the sea wave.” said Ronnie. The sea wave was flapping slowly and continually. “ Yap, what a beautiful place it is. The sea odor smells so good and fresh. I especially enjoy going to the beach.” said Angel. They played the volleyball at the beach, talking happily and enjoying the precious and valuable moments. After playing for a long time, they decided to take a rest and have some snack. However, all the shops were closed at noon; therefore, they went back to their hotel. Unfortunately, all of them forgot to bring their keys. Standing outside the hotel, they figured what to do next.
