From Create Your Own Story
You stir at her question. "Anna, go back to sleep..." She responds by looking at you with those puppy dog eyes of hers.
"I can't! The sky's awake which means I'm awake!" Anna whines, flopping on her back dramatically to emphasize her speech and absent-mindedly putting a lot of her weight onto you.
How do you react?
