Kinda lighter hot take: teens being scared to talk to their parents isn't them being "difficult."
Kinda sick of seeing parents talk about how their kids are "difficult" or "bad" for hiding things when they get judgemental and rude over every little change that happens. Might just be because I'm a teen, but if I trust someone then I tell them everything, doesn't matter if they're a family member or close friend. I only shut down and immediately lie about decisions or hide parts of myself when I feel like the first thing you'll do is be a dick or get mad at me.
Most of my peers are basically the same, the ones who have good relationships with their parents will make time to gossip or talk about decisions, while teens like me or my friends who are distant from their parents usually hover around a subject but lie and hide whenever it gets noticed. A ton of my friends have tattoos behind they're parents back, a lot of them drink/smoke or even hide mental struggles or life changing decisions. Not saying parents should let they're 12 year old get a tattoo, that's not ideal, but what I am saying is that maybe if the parent didn't talk so harmfully about tattoos and explained it in a neutral light instead of a negative one, maybe you're 12 year old wouldn't get a potentially harmful tattoo.
(Context I'm not 12, a tad older but I know 2-3 12 year olds who brag about drinking and getting tattoos. I drank at 12 too but that's kinda for another day.)
