Hi all, i'm in a bit of a muddle. Teen not yet 16 wants to spend £300 on a computer screen, with crypto currency he's mined (which in his eyes means he's earned it and it's his to spend how he likes). Honestly I think £300 is an obscene amount for a teen to spend on a screen. I said he's spending half only (which is still too much imo) - £150 - and putting rest in savings. We're at a stand-off.
Even having said if he has that amount to throw at a computer he can buy his own clothes from now on has made no difference but we got a load of sarcasm. Probably he's a bit surprised, but he's not budging.
I've been down the 'i'm your mother and you'll do as I say' route. I've tried appealing to his charity - i even said 'fine, buy the monitor but you'll be filling a trolley for the Food Bank after'. AIBU?? He's learning about money, he's learning about computers - he wants to work in tech.
TL:DR can i stop my under 16 teen spending on something I don't agree with if it's money he's earned?
Thanks
