I don't think it's a new trend. We used to try to get the teacher's riled up until they cried. The difference is, they now have cameras and can post it.
Kids don't change all that much, electronics change everyday tho.
I never tried to rile up a teacher.
I didn't want to have to tell my parents why I got kicked out of school.
My mom should have been put in charge of the CIA because she could get a confession out of anyone.
We were brats but we were high school age and I am assuming these kids are too. They aren't any brattier than we were. The kids know when they can get to you.
We went into one class and everyone turned their desks around facing the back. This particular teacher just walked to the back and started his class. Funny. School is usually boring so kids try to stir things up.
