The Phantom has a question for Christine relating to texting acronyms. Christine answers, and yet he still doesn't realize the answer...

Erik walked up to Christine, holding a cell phone in his hand. "Dear, what do this terms mean? Raoul is telling me I should be more proficient in my learning of this texting business. What does IDK, LY, and TTYL mean?"

"I don't know, love you, talk to you later." Christine answered, proud of herself for knowing the answers. Erik sighed. "Ok, I love you too, I'll just ask Raoul." He walked out of the room.

Christine blinked in surprise, before she realized. She giggled to herself. "That'll teach Raoul to try to get Erik into texting."
