Your absolutely right, they are, and I respect that you have your reasons. What I do have a problem with is telling others to practice something you have yet to grasp.
And while I also agree that actual age doesn't matter, at 13, theres alot about movies you probably couldn't appreciate, and that's by no fault of your own, because I'm 26, and there's still alot that just doesn't appeal to me, but at the same time, just as much that I have warmed up to by making myself aware and familiar.
