article: My name is Anna. I live with my mother and brother. I don't want my brother to play with my toys . My brother is not happy. My mother tells us to make some rules. We talk about the rules together, and then we find some paper . We write the rules on it.
  Here are the rules at home.
  *Be friendly to everyone.
  *Say please and thank you.
  *Play with the toys together.
  *Keep the house clean.
  I like these rules. After that, when my brother plays with my toys, he always says thank you to me. And my brother and I often clean our house on Saturday, so we can keep the house clean.
