Alright so, I'm an 18 year old, still in highschool, and I am 25.3% Cherokee Native American. Not long ago, I received my check from the Cherokee nation, which was [REDACTED] amount of money. While I won't disclose the exact amount, I'll tell you, it's probably a lot more than any 18 year old just gets at once. Especially one that's still in highschool and unemployed.

Anyway, my dad brought me up to a Navy Federal and walked out while I set up the account. I told the lady who was helping me set it all up that my dad's name could remain on the savings account that my dad had set up for me, but he couldn't have any access to my checking account.

This made both my parents angry, especially my mom, who demanded that I was supposed to show her my bank account and all my spendings at any given time that she asks (She hasn't doubled down or asked yet, thankfully, because it would become an argument).

When my mom told me this, I got angry and we argued about it. I told her she legally couldn't do that and that she can't make me do anything, and that I'm 18 and an adult now. She told me I live under her roof and that I'll do as she says. It was about a month ago, but the argument has been on my mind since.

She told me that I can be a legal adult and still not be an adult. Which I understand that concept entirely. I know I'm not prepared to be an adult right now. I'm still stuck in 12th grade and haven't even made it through the first year old adult hood technically speaking, so I understand that I am NOT MATURE.

That said, I personally believe that she can't just demand to look at my financial stuff, even if she does feel that "I'm still just a child". Not to vent, but I feel like I'm only seen as a child or an adult when it's convenient. When I do something wrong, "I'm an adult/nearly an adult and should know better" or "You are taller than your dad by now, you are pretty much a man now!", but when it comes to responsibilities like money, those arguments suddenly are negated and it becomes "You're still a child and don't know what's best for yourself".

I told my mom that I am mature in some ways since I have been keeping all A's (or mostly A's aside from a B here and there) and do chores without being asked and try to handle my responsibilities. But it doesn't feel like I'm seen as someone who knows how to keep their act together, because things that I did at like 15 years old were brought up as a testimate to my current maturity, same with my dad, except he brought up something I did at 13!

I don't think I have to show them anything. AITAH?
