Allie says that it always makes her laugh, since I'm one of the more exceptional students in the university. I'd be lying if I said I d...

"Ha! Did see everyone's faces?!" Allie exclaimed, laughing as she, Kona and Gwen walked back into the redhead's room. As was the norm for her, she was blushing fiercely. "Everyone was staring at me."
