OMG I am so sick of seeing this kind of shit.
Boo hoo.... everyones' parents are sooooo terrible....

Guess what.
Moms don't like (or need) to take 'constructive criticism' from teenagers. Maybe when you get out of the house and she starts looking at you like an adult, you can change your relationship to include those sorts of discussions. But take it from someone twice your age, it's going to be YEARS before you get to that point... until then, enjoy the fact that she is there for you, because that's more than a lot of kids get.
