if i am talking, it is mostly about arguing over my mothers common sense lectures, or i am giving my mother academic lectures XD
otherwise, it might be over games or television.

Nothing. I avoid talking at home.

I tell my Mom everything, she is my confidant. My Dad...not so much, pretty much it is just trading insults, none too serious it's mostly just being Smart-Assy. With my older sister I just talk about stuff....mainly inside jokes and music, anime and other such things...
