1. That I'm not trying to be inconsiderate or annoying, I just have different priorities (scratching my mind's itch).
2. This one was a major source of my teenage behaviour problems (which were impressively minimal for any teen, but still, easily resolvable if they only understood).
Logic is a perfectly valid way to negotiate problem solving. There's 2 parents/4 kids in my family, and I'm the only T. Every little problem was negotiated by catering to feelings and values.
I can play that type of fairness now, but when I was younger, it was impossibly frustrating to try to figure out why no one in my house would solve things fairly.
I just thought they were all dumb until I was mature enough to realize that they simply all saw things similarly to each other but differently from me. I wish they had not always catered to the majority (F type problem solving) but sometimes solved things with dispassionate logic, simply because while I was too young to understand what was going on it was a major source of frustration and any behavior issues I had.
Recent Example: When I took a gap year, my sister lived in our shared nice bedroom and when I moved back she had it all to herself and I was stuck with the basement bedroom. No big deal.
But then when she left for university in another city, my sister cried because she had an emotional attachment to the room itself, so my dad wanted me to let her keep it despite her only being home for summers/holidays.
Then I must have been a little hormonal or bottling up emotions for a long while because I broke down, ranting about how just because I don't share my emotions doesn't mean I don't have any... I had never made a comment about how much it sucked to live in the crappy basement bedroom because it was completely logical for me to live there. Which was the overarching problem--I would suck it up if I could see the logic; everyone else vented their emotions, and decisions would be made on emotions. This made me angry and hindered my rate of maturity because it grated on me over and over and over with daily small decisions.
3. I wish I had been pushed to excel. My family's all about balance, which I value, but I like the rigor of achieving all that I'm capable of, and I'm only learning to develop the self-discipline necessary to do all that.
I think the NT's "competence" need was not properly fed, and in fact, unintentionally repressed by my parents. I have higher self-esteem when I'm really grilling down and working hard for something. I wish I wasn't also having to learn basic self-discipline, because I was allowed to coast through school. My parents didn't even look at my grades, they just saw the honour roll certificate and said good job we're proud of you, and I didn't develop any good habits because I only worked hard enough to stay on the honour roll. They didn't push high standards on me, which as an NT I think is healthy (presuming it's in the right realm--I plan on entering academia; high standards in sports or art or whatever your kid is interested in would be helpful, IMO).
And while I would agree with the "because I said so" being a terrible phrase to use, I think sometimes it's okay to simply say "I can't explain why to you at this point, I need you to trust me on this one, can you please honour that." So long as that's used sparingly, respectfully, and you soften that blow with a small gesture of recognizing our maturity (like letting us in on something we normally wouldn't be allowed to partake in, or telling us something else that normally we'd be kept in the dark about) that'd have been cool.
