Adults Have First Names

I remember having a conversation like this either when I was in college or had just graduated. It's really weird to start calling people by their first names when you've been using titles for the past twenty years or so. And then you also have to learn their first names, not just Mr. Williams or Melody's Dad. Yes, that's a sci-fi reference there. And then you're working with these people in ministry and kids start using a title with your name and it's weird and you've joined the other side! Now you're gonna start sympathizing with the parents in children's movies!

D: So, Mr. Williams -
R: Call me Rory - you've graduated college so you're an adult now.
D: ...am I?
