Society in decline

On the train ride home yesterday, a group of kids got on the train, and for the short 5 minutes they were on the train, I think I may have heard more foul language than I've ever heard in my life. And these were just kids people, 10-14 years old. Back when I was a kid, we dared not even utter something like that under our breath in public. Why? Because we'd been taught it was wrong, and we knew we'd get caught by our parents or another responsible adult whom would report it to our parents. Where have our values gone?
