Dear meanies! 

The girl you called a slut for being pregnant. She was raped.
You know that boy you pushed over earlier? Committed suicide last night. 
That girl you called fat? She's starving herself. 
And that boy you teased for crying? His mother died. 
You know that man you made fun of for his scars? He fought for our country. 
That man you stole the little leather pouch off? He was homeless. 
And everybody else you've been mean to? You've either hurt them really bad or ruined their life.
