Formal

Graduation was a formal happening. Everybody was wearing the best set of robes they had and the tradinational Hogwarts hat. It was a tradition that you wore it when new students were selected and when you graduated.
Percy looked at the person sitting next to him, Oliver Wood, and they both smiled.
“Congratulations, Perce. I knew you would get into the Ministry of Magic.”
“Thank you. Did you get into a Quidditch team? Which one did you want again?”
“Puddlemere United. And I got in. As a reserve player though, but I still got in.”
There were even formal conversations.
