My name is Jennifer and my little sister’s name is Stephanie. I’m 8½ years old and Stephanie is 7 years. Santa our behavior this year have been excellent. You can ask my mom if you want. Please Santa bring me some clothes. I’m 10T and my shoe size is 4 and Stephanie is 8T shoes size 2½. Please make my dreams come true for Christmas.
