For example, my colleague has a tendency to talk too much in class, which isn't a trend in our profession. You see, we are oral English teachers, and she tends to use valuable class time to go on and on about this or that aspect of grammar--even off-topic subjects, like how trendy and up-to-date she is with what's new in music and fashion. "After all," she tells me, our students are in university and so if I want to reach them, I'll need to show them how with-it I am." Her monopolizing class time doesn't allow her students time to practice speaking English.
