Betty blinked her confusingly and asked," Why!.. Why don't they exist?"
Martha eyed the little girl and noticed the puzzlement on her face. "Because it's just a story and people inside the story don't exist. They are just imaginary characters"
"Oh.." Betty sighed when she finally understood her words.
Martha watched her fall silent, and she quickly took the opportunity to avert her mind. "Okay now Betty, it's time to sleep" she said and watched her girl gasp at her before she let out a small pout.
"But Martha... you promise telling another story" Betty begged with her innocent voice.
Martha couldn't ignore her cute plea and gave in. "Yes I will but you have to promise me that you won't nag for another one and go to sleep" she asked.
