C

Kevin and his family had a holiday to his hometown—a very beautiful island. It was a great trip.

They all wanted this trip. Kevin's parents wanted to go out into nature after a long time of work. Kevin needed to take a good rest before the exam. Kevin's brother Jim is in the first grade, so he doesn't have a voice in family things. He was just happy that they were going outside.

The sea was blue. They went boating in the sea. It was so cool. There was no Internet, so they spent the whole time together. They stayed in a small wooden house by the sea. Mom and Kevin cooked delicious sea food. Jim ran after chickens and ducks, and gave them food. When he became tired, he sat next to his dad and helped him fish. He even helped to hook two fish!

It is always good to spend time with families. They liked this trip!
