Movie Etiquette

I was so excited to finally get to see Twilight part 1 in the movie theater. I mean i was geeking out to the highest power. I usually only get to see them when they finally come out on DVD. But now I remember why I wait.......Do people even care about others anymore I mean good god I had a 10 year old behind me translating the whole movie to her mom in Spanish loudly I must add. Then someone brought there toddler and let him/her run up and down the isle steps squealing through the whole thing. I am not making this up I couldn't this is to far out of my realm of rudeness. I was getting so mad that I was about to start a fight with said 10 year old because I couldn't hear a word the movie was saying I wish I understood Spanish so maybe I could have followed along. But I just turned around and shushed them but it didn't stop them people are just so rude these days I would never bring my baby to a movie theater and my kids were trained at an early age no talking in the movie.. I just thought that was a common rule taught to everyone but alas I am wrong again. So now I have to wait till it comes out on Friday to buy it so I can watch it again. Not that I wasn't going to buy it anyway but it's not everyday I get to got to the movies that's not rated PG. So I walked out of the theater two hours later deflated and melancholy with a dash of annoyance. What did I learn from my experience save the $12.00 and put it towards the DVD.....
