A loving world?

   If everyone loved each other like they loved themselves it would be such a happy world. No one would fight or argue it would just be peace and love.Every thing wrong with the world would just disappear, because who would want to hurt someone they love.But if you think about it there could be fights.I mean someone might say "I love you" then other person could reply back with "I love you more", then the first person could say "no i do".Then that could turn into an argument of who loves who more.So I guess the world won't be so calm after all.
