Are little kids nowadays different to you?

In my hometown a teenager (15 I believe) stabbed a 13 year old girl and her 18 month old brother Sunday morning. I then went on facebook to see people’s comments on it. One of my friends said “I saw a fourth grader cussing! When I was in fourth grade the only word that was bad was shut up!” I’ve noticed this, the new generation of kids has changed a lot. I’ve heard that our 6th graders have drunken and middle schoolers have sex! WTF. I had sex when I was 17.. not 12 or 13.. what do you think about this? Is it to do the media or bad parenting? I’m mind blown.
