Not all teenage girls are ungrateful narcissists.

My sister, though sometime annoying, was outright amazing to me. We are a few years apart, and even I wondered sometimes why I got to hang out with high school kids. Not all teenage girls are the same, and some need to be shown they are ungrateful. Some go through a phase which is cool, other are just horrible.

That is the flippant attitude about behavior that makes them think they can act like that. Also, if your kids are peeing on things, then you need to really rethink your parenting style. I had my dramatic moments, because **** hormones and puberty, but my parents demanded respect and my attitude was not acceptable. I learned when my mom said, "You are getting an attitude" I better stop talking or acting like that or I lost out on something fun. I am not sure how your parenting style is, but you are the parent and do not have to take that from your kids.

Normal to do it ONCE. And then you march that kid straight to the older sibling, and you make her apologize, in detail, for her behavior. And then you make her thank them, in detail, for all that they did. And the second time? Party is off. Ice cream cake is eaten by everyone BUT her. Presents go back to the store. ONE teenage-bitch moment every few months is normal. But as a parent, you don't dismiss it. You step up to the plate, you parent that kid, and you draw the line at that sort of behavior. And there is a big fat "Or Else" backing it up too. Cell phones can be sold, routers/modems can be password-protected, after-school activities can be dropped. It's only typical-teenage-girl behavior once in a blue moon. More than that? Either the kid has issues, or the parent isn't parenting.
