Something I found on another profile here and I 100% agree with it:

The girl you called fat? She starves herself. The girl you called ugly? She spends hours doing her makeup so some people will like her. That guy you laughed at because of his scars?  He fought for this country. That boy you punched in the hall today? Committed suicide a few minutes ago. The boy you just tripped? He is abused enough at home. That guy you made fun of for crying? His mother is dying. That fourteen-year-old girl with a baby that you called a slut? She's been raped. The boy you called lame? He has to work every night to support his family.

*So think before you make judgments. I'm not saying we're saints and we never do this because I know we do, but think how your actions will affect others. You never know it might save a life*
