kids are very blunt in their honesty, naivety and cruelty in my experience.I'm sorry.
If you act like an asshole, you'll be ostracized or killed. Period.
The nearest thing we have to a post-apocalyptic society, from an ethical standpoint, is prison. If you owe, you pay up. You don't rat or play games or you pay the price. If you're alone, you're prey unless you are a bad-ass enough predator to afford the luxury of being alone. Weakness is to be despised. Weakness means death or worse, living-death, slavery, WORSE. Skills that people need will always be valuable, whatever the currency. And NO WHISTLING. Whistling will get you killed, songbird.
