Ade and Boo
Adrian raised a brow. He didn't recognize the greeting. It was as exotic as the girl looked. She had his full attention. He was curious that he didn't recognize her, but she must be a student. He knew there had been new students coming in, even right at the end of the year, so he could only guess that she must be new.
He recognized the name when she gave it, remembering it from the journal. His smile grew. "Ah, yeah. Boo. I'm Ade." He was assuming she would recognize his name as well. "Enjoying the party?"
