Report card?

my dad lives in maine and i just got a report card wih 2 Fs 2 Ds and a C+ so i was wondering how to break the news to him over the phone. My grades are always pretty vbad but thi is the worst of the year. And please when you answer this dont lecture me on how its my fault about the grades and whatever you want to say because ive been brought up by my mother and we dont believe in the school system and im probably just goin to be homeschooled next year anyways. So i would just like some advice and if you were wondering no he's not in support of the homeschooling as a matter of fact he doesnt even know yet.
