My speech craft role model is my parents, more so my dad. He knows a thing or two about presentations and speeches because, as the Head IT manager at Lassus, he has to give quite a few to his superiors. When I am talking to him, it can be quite entertaining as he is considerably bubbly. I do not get to hear many of his prepared speeches, but I can say with confidence that his ability with impromptu is impressive. When one of my brothers, mom, me, or someone else is down on themselves, he has a way with words that is helpful. I will hopefully inherit at least a little of his speaking ability.
I can totally see all of these traits in your father. He certainly has a way with words that is motivating.
