Bullying.... An ageless problem.

I think that as you are hurting someone's feelings, there should be an instant sense of that persons pain and sadness in your own body and mind.  Maybe then we would think about the things that we say and do to others before we allow it to come out of our mouth.  Bullying is a ageless problem. Kindergarten students can tell you how it should be.  

You should put yourselves in other's shoes before you judge, and if you don't have anything nice to say, don't say anything at all.
