Each year, we all have a special day (our birthday), and we enjoy it for we know it will be gone in twenty-four hours. Arlo is turning three, and his parents are throwing a birthday party for him. He has invited his friends over to celebrate with him and his family. They are having fun playing in the backyard, eating cake, and opening presents. And when Arlo's birthday party was done, he couldn't wait for his next birthday to come.
