If I walked around with confidence ie with my shoulders back, head up, chest out, I would be percieved as arrogant. "oh look at him, with his big bald head and goatee, he thinks hes so big!"
You being serious? see this is why i think sometimes you are paranoid...again i said sometimes not all the time...this paints a picture in m mind of you walking down the highstreet and noone is doing anything but you think "oh i cant act confident otherwise they call me arrogant" if im wrong then my bad but it is what i think.
