It makes me so angry when people hurt other people. Either physically or mentally. I just wonder where people get the impulse to shout out words to purposely hurt others. Even if you call people 'fat' or 'stupid' as a joke, it can still affect them and make them think horrible things about themselves.
So, just remember, when you are starting to think you are useless or inimportant, then you are dead wrong. You are beautiful in every way, and the world would be awful without you.
