The first thing that Yoongi had noticed when the door had opened was that this new Professor stuttered. Was he just nervous or did he suffer from stuttering? Instead of asking this though as he figured it would be incredibly rude for him to do so, Yoongi smiled instead which broadened when the man mentioned he had been a Gryffindor as well.

"I'd love a cup of tea" he said as he entered the office. He immediately looked around. He had never been in the office of the previous potions professor so he couldn't tell if it looked much different. "I uh.... i wanted to say welcome to Hogwarts" he said as he still looked around before he looked at the Professor again. "And" he sighed heavily, running a hand through his grey/silver dyed hair. "Also wanted to apologize about the start of term feast. That was probably not the kind of welcome you new Professors had wanted" He hadn't done anything except try to stop them but he felt that, as the Head Boy now, that the responsibility was part on his shoulder as well. "Is this your first time teaching, Professor....?" He suddenly stared at him. "I'm sorry i don't know your name, sir"
