This is an interesting subject. Working for a series of high
caliber store dealers, I see characteristics of arrogance they
possess. I think it's from their need to present the presence
of authority and often to show that they are a big step above
their subordinates. It's also bragging rights about what
people accomplish over others, but in a way to also show
they have more or are better. Human nature, I suppose.
If they are less confident, often arrogance rears it's head,
Because of a sense of neediness.
Most times confidence just shows when a person want others
to know that they know what they are doing. Sometimes
confident people don't know what they are doing, but still
give that impression.
