"I'm not sure if I know you. Have we met before?"

A quiet yet polite voice could be heard from a young man that stood in front of you. It was clear from his tone that he didn't really want to waste his time chit-chatting with a person he barely acknowledged, as his brown, tired eyes studied you up to down. Eventually, he just adjusted the collar of his green coat and spoke again, now more confidently.

"If you have something to deal with me, speak up. Otherwise I'll have to ask you to come up next time. My lectures aren't gonna be listened by themselves."
