Familiar steps perk her ears. **The boy! The boy! It's time for him, must be him. Hello!** She jumps to her feet, whining in anticipation. She paces back and forth in front of the door and performs a premature play-bow. **Come in! I'm ready!** The boy is shouting, something about the girl, but she's not sure. **Hey! Come in! Let's play!** Unable to control her growing excitement, she begins to bark. She tries to keep in down, but sometimes it is hard to be a Good Dog.
The girl comes over and opens the door. **Greetings! Salutations! I will lick you, oh great master! I have been waiting forever.** She tumbles over the boy and he wrestles with her. They get up and go inside, and she stays by his side. He says angry words to the girl. **Why do theses littermates not get along? This is not play-fighting.** She follows the boy into the living room.
