From "Boston Public: Chapter Forty-Five (#3.1)"
[after Colin turns around sharply after talking with some students
] Mr. Flynn.
[politely with a smile
] You can call me Colin.
] I'll opt for Mr. Flynn, but thank you. I would prefer your students also call you Mr. Flynn, Mr. Flynn.
] Oh, I-I actually kinda told the kids that I prefer Colin. Ya know all that mister stuff really...
[cutting Colin off; seriously
] I know you want to be their friend Mr. Flynn, but that's not how you get their respect. Stay on this course and you will lose control of your class.
