As I read down the discussion threads, I noticed a few people addressing an issue of young age, or of being a novice instructor, and consequently being challenged by students. Fortunately, I have not had to deal with that in quite a while; I learned how to present myself, the class room, and the subject matter so as to minimize that in my 4 years as a public school teacher. My issue lies almost solely with some students wanting to be too personal either in or out of the classroom, and it took me by surprise a bit.
