Arrogance

Watching the newer episode of American Chopper.  (Senior vs. Junior)

I don't know if I have the unmitigated gall to do something like this.  Your Dad taught you how to make it, and do your best job, and you fail, and he gets angry with you, so you directly compete with him?

I've been extremely competitive with my Dad, but I would never have the arrogance to do something like this.
