I'm currently 17 but turn 18 very soon. My parents are very strict and conscientious and it's very hard to get anything past them, especially money-wise. My mum always asks me to check my bank statements online and she will always be aware of any money which goes in and out of my account (including any money from a summer job, etc.) as long as I live under their roof. And I won't legitimately be moving out after university and it's not an option to simply not tell her about my finances, it won't work that way.
However, I would really like money of my own but this would be gained through ways my parents are not aware of, e.g my brother does a couple of jobs at university (such as working in a bar) and whilst my parents are not approving of this, they definitely would NOT let me partake in any work like this (my parents are super strict with me because I'm a girl). But, I seriously need money and feel like I deserve the freedom to have and earn my own money seeing as I will be an adult!
I'm very inexperienced with banking though, and I was wondering how do I create my own account, but also in a manner that my parents will be unaware of (e.g. I can't receive letters to my household otherwise my parents will find out). Thank you! (And sorry for posting in relationships, has to be anonymous!)
