Chris- Some Kind Of Ghost, Maybe

3, 2, 1, briiiiiing! Sounded the lunch bell. All the other students left in a rush, but I stayed behind, smiling at the nice score I received on a recent test.
“With this last test, my final grade is now an A” I said, to no one in particular. But someone else overheard, “You like to brag about your educational achievements?”
I blinked and turned to face the speaker, then scoffed, “Of course not”
He laughed once, then said, “Is that so?”
I nodded defiantly, “’Tis so.”
He laughed again and nodded back, “Alright noob, cya around.”
I frowned and shouted a bit, running after him, “Hey wait!”
He stopped, “What?”
“What’s your name?”
He answered simply, “Nolberto. Goodbye.” He waved, then walked down towards the cafeteria.
I tilted my head in thought, How odd…. I’ve never seen him around before.. I shrugged, “Oh well, whatever, I’m probably never gonna see him.”
“Are you talking about me, noob?” he was suddenly behind me and I turned to face him again in surprise, “No of course not!” I said, shaking my head.
He grinned and laughed more, “Alright then, cya”
I growled lightly under my breath as I picked up my stuff and ran upstairs to my next class, totally skipping lunch.
