I Want To Buy Something With My Own Money, But My Mum Says No. What Do I Do?

If it's your money, that Ты earned, Ты have the right to do with it as Ты will.
So fuck her, buy what Ты want.

Just let it go.

when i want to use my own money and mom and dad says no. i just let it go and wait til Далее time.
или something like; "But what if i do/dont ..."

It depends on how badly Ты want it.

Why doesn't your mum want Ты to buy the hat? Is there something wrong with it? And why did Ты have ask her in the first place?

I can understand parents not wanting their kids to buy all sorts of crap that will mess up their house... say Ты wanted to buy a giant розовый Пианино (I dunno.. I panicked), that could be understandable because that would take up so much Космос and be super annoying. If there is nothing offensive about the hat, explain to your mum that Ты believe Ты deserve to buy the hat, because Ты worked hard to earn the money to buy it.

buy it anyways...it don't consern her, it's ur money...

Yeah, my mom does the same thing. So I ask my grandma and my mom says fine buy it, just stop asking your grandma for things. It works every time.

Just go by yourself. She cant stop u if shes not there.

That happens to me all the time...
If Ты really want it that badly and think it'll be useful, keep asking her every so often until she finally gives in. And try to give her some reasons that might persuade her. But, don't ask her every секунда until she gets so annoyed, she'll most likely not let Ты get the hat.

Okay, so buy it. I read over your Комментарии and Ты need the credit card details right? If Ты have your money in cash, tell her that you'll give her the money after Ты use the credit card so it'll be a fair exchange for it. Like Ты take the amount of money off the credit card and give her it back in return (like pay her it back) it's worked for me before :D
