Most of us want to please our students and do what we can to make their aviation experience more fulfilling. There comes a time, however, when it's appropriate for instructors to just say "No." We should keep in mind that we are paid to be instructors because we know more than our students do. Though they may not think of it that way, students hire us to provide the judgment and knowledge they lack, and it is our professional obligation to do so. It is also our primary obligation, even higher on the list than pleasing the student client.
