As a parent, you shouldn't be affraid of your kids or worry about their angry attitude. After all why would they be angry? Today's kids get the whole world served up on a silver dish, if you know what I mean.
You think that kids today get served the world on a silver dish? Can you puff puff pass that over here, because dayum.
Our children have seen horrific things happen like wars, bombings, and ecological events like Hurricane Katrina, the 2004 Tsunami... and it makes them angry. They see it everywhere they go, because media is prolific in their lives. And the clear response to the fear of these things becomes anger. They see parents struggle to make ends meet, and they watch their heroes and idols on TV going to jail or getting busted for steroids, drunk driving, drugs, and violence. And they get angry. They see governments paying for things that they will have to pay off in their lifetimes but have parents who can't afford college and they get angry.
Teenagers are young adults. They are old enough to understand the ramifications of the worlds events, and too young to take and responsibility or do anything about it. Teenagers are going to make mistakes, the same mistakes we would make if we didn't have the responsibilities that we do. It's a bit of escapism from the harsh realities of their lives. Most teenagers come from middle class homes, not upper class mansions, and the truth down her ein the trenches is a hard one and I don't envy the next 70 years of their lives.
I trust that I have raised my children to have common sense and make the right decisions for themselves and I haven't been proven wrong yet. My kids make good choices in peers, and have built good support systems around themselves. They speak to me honestly and frankly about things (girls, drugs, other kids problems) because they know I'm not going to fly off the handle and get angry. When my son is old enough to bring it up, I will have a discussion with him about weed and will explain to him that I'd rather have him try to smoke a joint in our house than out driving around and doing something stupid. Let him experience how it effects his motor functions and mindset while he's somewhere safe instead of where adrenelin can make the experience seem more out of control. I don't see the harm in it, and the more you come down on kids, the more they will hide from you. The less you trust how you raised them, the farther they will drift away from you.
I will not let other children in my house to do anything illegal though. I will not throw parties, and there is even a paddlock on my beer fridge in the garage. I trust my own kids, but I know that other parents are idiots.
So what if another parent finds the stash and calls the authorities? I'd find my child a good lawyer if it came to that and defend him. Why would I ever tell anyone about what I found anyhow?
