As you've probably learned from every movie featuring an idealistic teacher with a job at an inner-city high school, it's impossible to do the job well if you can't find a way to genuinely relate to the students you're teaching.
High school teachers willingly sign up to deal with pupils who are in a period of their lives when the only thing more important than constant levels of apathy is the thought of someone maybe touching their genitals over their pants.
With that said, developing a connection with students can be slightly difficult.
In my experience, the best way to gain respect is to say "ass" or "sh*t" every once in a while or show a genuine appreciation for the music of Lil Wayne, but I'm not sure if those are still methods being employed by the current generation of teachers.
However, I do know there's been a disturbing rise in the number of educators recklessly incorporating ever-popular "memes" into their lessons and accidentally teaching their students more about cultural appropriation than a history book ever will.
