I was that teen for a long time... I'm still embarrassed by how bad I was. Let me tell you something, young adulthood is a real shock when you've never had disipline. Do you kids a favor and teach them how to obey.
You know, just because you don't spank, doesn't mean their is no discipline. I have never hit my kids, but they are disciplined when ever they need it. Which, now that they are not toddlers, is much easier.
I watched a mom hit her 3 year old with a stick the other day. She was letting him walk around with this long stick, threatening to poke everyone in the eye. When he finally poked his mom in the ass, she ripped it out of his hands and hit him with it. Then he picked up the stick again :shrug: he learned nothing and she looked like a jerk.
