     Jack is my new classmate. He lived in a small village for fifteen years. His father, Mr. Brown, was a rich

farmer. Last year his father opened a shop in our town and last month he bought a big house and Jack began

to study in our class. But Jack had few friends here. At first he often played by himself.

     Jack's neighbor Daisy is a kind girl. She found Jack never talked with anybody and decided to help him.

Jack likes to stay with Daisy and talks to her a lot. Now they're good friends.

     This morning, Daisy said to Jack, "It'll be my sixteenth birthday tomorrow. I'll have a birthday party. Will

you please come?"

      "Certainly!"

      Jack said happily. Jack got home and thought of a present for Daisy. But he forgot to ask Daisy what she

liked. He couldn't call her because he didn't know her telephone number. At that moment Mrs. Brown came

and asked, "What's the matter, dear?"

      "What would you like if it was your sixteenth birthday, Mommy?"

      "Nothing," Mrs. Brown said. "I just wish I were16."
