What is it with kids these days?

Ok, I am sure I sound like an old lady when I say that but after people watching yesterday at Great Adventure, I am not sure I am ever going to let Jenna or Emily out of the house when they are pre-teens.  I can not get over the clothes (or lack there of) that some of these girls were wearing.  Now, I know I am going to take a lot of heat for saying this but, more importantly, what is it with parents these days?  I know most of those girls were not old enough to have jobs to make money to buy their own clothes so I know the parents are buying the clothes for them.  I just don't think it's right for a teenage girl (if she was even THAT old) to be walking around with her butt cheeks hanging out of her shorts!  Sometimes, having to buy that medium isn't so bad if it means your daughter's @ss is not on show for everyone and their mother (or father)!
