The girl you called fat: 
She's overdosing on diet pills. 

The girl you just called ugly:
She spends hours putting on make up in hopes people will like her. 

The boy you just tripped:
 He is abused at home enough. 

See that man with the ugly scars:
 He fought for our country.

That guy you just made fun of for crying: 
His mother is dying.

You don't know what you think you might. 
Don't judge.
