I'm 17 and I fight with my parents a semi-good amount. I tried to avoid it by keeping my mom updated on my life and being open with her..but it really hasn't helped much. My 21 year old sister still fights with my parents, but I think it has a lot to do with parents not learning what to do and what not to do. If they learn that a certain thing they say, or a certain way something is said makes their kid mad..they don't stop doing it when they should approach the matter from a different angle perhaps.
