Something that happened in the past.
Two weeks ago, my parents and I went to the beach with my cousin's family. We had been there for a whole day! Firstly, we swam in the big, blue sea. Then we picked shells by the sea shore. There were so many of so many different colours. Finally, we had a grand picnic there on the golden sand. And all of us went home after the sun had set. That was so much fun!
