Where are instructions for a teenager?!

I love being a parent most of the time but days like today....! One kid has some friends that are not making the wisest of choices and these are the kids that are "fun" and he wants to hang around with. Time to be the enforcer! How do you get through to them that these types of kids are always going to be these types of kids as adults? They never seem to grow up or go anywhere in life. Kid #1 has some really nice kids he hangs with and he has a good time with them but every now and then he heads over to the naughty kids. Kid #2 is in the middle of the teenage angst and like his parents doesn't know when to keep his mouth shut. He seems to always be in a rotten mood and today is no different. Then we get to #3. He pulled some major temper tantrums lately and therefore is grounded from going to his friends house this week. So he pouting and stomping around here. I'd love to be the "nice and fun" parent and just say "It's ok let's just forget everything". It would make my life easier but then what does that teach them? Next baby shower I'm going to I'm going to find the instruction book and give it to them. Like my mother always said "when you have little ones you have little problems. When you have bigger kids you have bigger problems." I just didn't need them all at once!
