Bullies and fairweather friends

Why do we blame the ones trying to be "funny" and "cool" and let the others go? You see bullying and you don't try to stop it or get someone who can stop it - you're way worse than the insecure bully with a complex. Especially if you're a friend and you can't stand up for the person of whom you claim to be a friend. Humiliating someone or insulting someone is just as bad.
Yes, we throw words at the ones who know us and love us. But no, you do NOT pick on strangers, you do not pick on nice girl who talks too much and appears attention seeking to you, you do not pick on the boy who barely stays awake during the day, you do not pick on that girl who never talks unless spoken to.
How would you feel if you heard people you barely know judging you for trying to be optimistic? They don't know if your parents are getting a divorce and leaving you behind like extra baggage. How would you feel if you heard the girl you were helping out with work tell others just behind your back that you're stuck up? Just because you are usually quiet and you spoke up and knew something she didn't when she asked. How about people mocking you for not being able to see straight without that 5 cups of espresso? They don't know you have a baby son at home to take care of. And all of those who were nice to you every other time, when they hear all this and stand near you saying *nothing*? That kills the worst.
You can stand up to bullies. They at least give you something to fight with. How do you fight against a festering wound left by silence of judgemental eyes and unspoken words? These fairweather friends. I pity you. No guts to stand up and no love to speak of. Because if you truly do love your friend, you'd never stand down and watch them get thrown under a bus.
Think about it. How many fairweather friends do you have? If the number is high, my dear, you better have some serious introspection to do because you might be one too.
