Carol's eyes turned wide open. She stared blankly at Mathew's face for a moment only to then avert her eyes as she blushed.
"That's..." the girl mouthed, raising her hand to wipe her hair behind her ear.
Mathew crossed his arms in front of his chest and waited for Carol to continue.
"That's something very personal," the girl eventually said, suddenly sounding much more formal than before. "I don't think it's appropriate to discuss such things with someone I'm not close to."
"Oh, come on," Mathew urged her, leaning forward a little. "It can't be that bad."
Carol slowly shook her head from side to side. She then raised her hand and started rubbing her temple as she furrowed her brows. It was clear she was troubled by something.
"It's not that I don't want to tell you," she eventually said in a small voice. "It's just... I can't think of anything new at this point."
