When I was in second grade there were two girls that my classmates and I picked on.  We were rude to them saying they had cooties and shunned them.  One day one of the girls had enough and broke down in tears after recess was over.  When Mrs. Williams learned what happened she had the two girls out of the class then let us have it.  She was so angry and disappointed with us.  She made it very clear to us how horrible our behavior was and how severely it impacted these two girls. 

Our class received the message and our class continued our elementary education free from bullying.
