Back when I was growing up, when my friends and I wanted to do wrong, we all knew it was wrong. There was a constant sense of looking over our shoulders to see if someone was watching us.
Today, when our kids are pressured to do things that go against our family’s values, more than likely their peers consider it “normal” behavior. They don’t see anything wrong with it, so they don’t understand why your teen would have any problem with it. That change makes peer pressure much harder for your teen to resist.
