>boss is incredibly arrogant but thinks he's humble
>everything has to be done his way, interrupts you to correct you in sentences
>interrupts you to question why something was done this way or why a deadline has moved back before giving you a chance to explain the external factors that have nothing to do with you
>when something goes well its thanks to him, when something goes badly its thanks to you
>overhear him talking to a coworker today and he said "I'm the most reasonable person you'll ever meet" without a shred of irony
>almost died laughing

Can /biz/ enlighten me why he's like this? Is there another side to this where I'm the idiot and he knows what he's doing?
