BR 2-02: A Monter Mistake

I read an English book. The book title name is ‘A Monster Mistake’. It looked interesting. So I was choice it.
This story is that Gran, mother and children went to Scotland. Gran painted a picture. She had painted a monster. And Gran wanted to play a joke on mother. They put the monster in the lake. It made the children laugh. I thought that it looked brilliant and it is what a good joke. And some people saw Gran’s monster. They took photographs. It is very interesting for me because everyone believe her monster. I may believe it too.
The next day lots of people came to the lake. They wanted to see the monster. And Gran told everyone about the monster. It was just a joke. Everyone laughed. I was surprised that I guess everyone maybe very angry about it, but everyone laughed. I probably be angry.
