Why can people be so mean? :(
sometimes parents beat there children and so this can cause bullying because there parents beat them and they think it is ok. This can cause bullying and general meanness. this is one answer to your question but there are very many.
Because they havent been taught the morals to respect and maybe they have but they dont want to respect others. Remember do unto others as the would unto you.
Because they don't know how to show other emotions
cuz they have no life want me 2 beat them up 4 you?
