Bully

What is a bully?  Clearly some one who forcefully intimidates you into giving them your lunch money or homework is a bully.  But what about saying something you consider derogatory or using words you do not like?  Does having to be so careful about what you say all of the time increases internal tension and stress.  The old saying "Sticks and stones may break my bones but words will never hurt me?" may be untrue but have we went to far in restricting free speech and ideas?

Is it bullying:

• For someone to call you a nerd because you do better than them on test?
• For someone to say you dress funny?
• To parody your speech?
• For someone to encourage you to do better?
• To call you tall (Wilt the stilt) or short (Oh, you are standing)?
• To parody your appearance?
• To laugh when you fall funnily?
• To show disgust when you tell a bad pun joke?
• To run a race faster than you?
• Refer to you by skin color?
• To make something you do or say humorous? 
• Call you a bully?
  

Who should decide if something is bullying?  The person talked to, the person talking or an unbiased reasonable person?

Where do you draw the line between teasing in fun versus bullying?
