I think that most people who read this genre want to read about a very polite teenager who is being victimized in some way but is saved from himself, or from others, preferably by a guy who is his age or slightly older, and who he ends up having wild monkey sex with. That monkey sex partner would ideally have a parent who is truly golden, who will intercede to help the other, troubled, monkey sex partner. When you bring in a more realistic approach, where the kid has real bratty tendencies, is myopic and self-centered, it doesn't play as well.
I have my own personal, anecdotal opinion on why that is. I think that unless you deal with your own kids, it's hard to understand this kind of conflict. I remember when my son was young and we'd go out to eat for family events. He'd be really antsy, and have a hard time sitting through dinner. (2-4 year olds are a real challenge when it comes to that). My sister and brother-in-law were just appalled at his bad manners, and how he couldn't sit still and not cry at a restaurant. Now they have their own 3 year old, and he's so bad they refuse to go out to eat with him at all. Now they get it. Same thing on airlines. "Why can't they shut that kid up?" people without kids are saying. People with kids know it's not that easy.
Teenagers don't usually cry in restaurants or throw tantrums on planes, but they have their own special challenges. It's easy to decide that they simply aren't being respectful of their parents or their elders. It's easy to forget that respect is earned.
Some will tell you that in their day, kids that were like Will would get the crap beaten out of them. That's why they didn't act like that. Kids need that kind of discipline. Spare the rod, spoil the child. In other words, you should break their spirit. In about three chapters, I'll show you what happens when you do that with a bright, and very high-spirited, free-thinking teenager.
