''When I was a boy of fourteen, my father was so ignorant I could hardly stand to have the old man around. But when I got to be twenty-one, I was astonished at how much he had learned in seven years,'' Mark Twain is rumored to have quipped. In ''Dad Was Right'' Brian David Floyd explores this common sentiment teenage sons often have towards their fathers, and the change of heart that comes once they too enter adult hood. In ten short chapters, Floyd conveys key life lessons his father taught him through funny and touching stories he recalls from his teenage years. Such lessons include the fact that hard work is a part of life...someday you'll actually need what they're teaching in school...why you must be smart when you have to fight....never being afraid to ask the prettiest girl to dance...and of course the importance of calling your grandmother. ''Dad Was Right'' is full of the wisdom fathers pass on to their sons, though it's often initially rejected. But ironically, it is these lessons sons will cleave to as they become adults and seek to pass on their children as well.
