Arwen's brows rose slightly at the sharp pitch in Selene's voice. If she hadn't known better, she might have thought she had mistakenly worn something that didn't belong to her. But here, she knew better.
"Ms. Martin, did you have a rough day today?" she asked coolly, her tone polite.
Selene only glared at her, her fingers curling tightly into fists at her sides. "I asked why you are wearing this necklace. This —"
"This is mine," Arwen cut her off before she could even finish. "Of course, … if not me, who else would wear it?"
"Arwen, you —"
"Ms. Martin," Arwen interrupted again, her voice firm but even, "I think you should consider taking lessons in etiquette. Because I am getting tired of reminding you of the same thing over and over again. This can't continue for long. Even my patience —though I have it —is limited. And in just few days, you have almost exhausted it all."
