If I were a teacher in an urban school - and I hate to admit it - I would probably let these youts play on their phones all period, while I sharpened pencils or filed my finger nails, a la Mrs. Wiggins.
I suppose, but after some time wouldn’t feel jaded, that you spent years in college getting a college degree and now you cannot draw an personal satisfaction in teaching youth, because they are monsters?
I don’t believe those youth would leave you unmolested very long, its not in their nature to leave anything un-tormented, including small animals or anything else they perceive as weak.
I was a HS substitute 25 years ago, my very first day in a portable building far from other classes 2 boys started a fist fight in the first 2 minutes of class. I just reacted, I shouldered one of them and pushed the other one down in a desk and yelled at them.
After things calmed down I realized what I had done so I just told the class to open their books. Other kids in the class started asking if I was going to send them to the principal and I said no, I think I handled it.
Nothing ever came of it but I got a reputation and a lot of respect.
