bully

How do you save yourself from a Bully? He or She could be your friend, manager, or partner. Time and again, in my short life, I have come across such a persona. Someone too dominating, I am always right or, It is your mistake kind people.

Are bullies broken from within, too insecure about their public persona? Did they had a troubling upbringing? Is acting bully: a sense of pride or ego boost for some?
