The Vampire Chronicles
"Talk to me, princess,"
I've gotten used to his endearments that I'm always expecting one after each word.
"I got really hungry earlier and I didn't know if it was for food or blood. How am I supposed to differentiate both?"
"If you're thirsty for blood, you will feel your fangs protruding out of your lips. But if you don't feel that, then maybe it's for water or food. It might get confusing at the start but you'll get used to it later, princess. Soon, without any effort, you'll recognize each thirst, okay,"
