Oh! The school I was a professor for is a boarding school, so all of the kids live there during class time. Everyone gets sorted in to one of four houses, and those are the people that they live with and go to classes with. The head of house is a teacher that is in charge of that house. So my rooms were near theirs in case anything happened and I was the one who made sure they followed the rules and stayed safe or talked to them if they needed anything after class hours.
