Do you think is embarrassing for 18-year-old do have a joint account with her parents?

So my dad decided to open up a bank account for me but it’s gonna be a joint because he can’t really trust me with a lot of money. He’s been teach me about money and I know value of a dollar but he knows I waste money I stuff I don’t need so my allowance has been shorter. My two best friends said that they’re getting their own big accounts and they been looking for work. Don’t people like my age have it own bank accounts? Every time we get money put in the bank he uses it for stuff and never gives it to me. I mean he does but he only gives me like a little bit because she’s afraid I’m going to waste it but I don’t waste money. I usually don’t wanna post about this but I thought I open up about it. My older siblings have their own. Of course because they’re both married. I asked my dad if I can have my own but he said when I’m responsible enough to handle money and he says I’m not ready because I wasted sometimes. 😒😔
I’m 18 not 12!
