Ds is 16 this month and we wanted to treat him. We decided to get him a PC and my dad said he could build one (he’s been building them for years), so we agreed. We spent £400 on some hard drives and another £250 on a monitor. Initially, Dad said he had bits lying around he could use but said to give him a couple of hundred pounds for other bits. The PC would be from us and my parents. Got a message from Dad yesterday and he’s asking for £500. He’s explained that he’d added everything up that he’s put in it and divided the cost between us, even though some of the parts were laying around in the back of a cupboard. Says he’s had to buy a couple of things, o e of which I know is less than £10. Too late to change our minds now as it’s already built. AIBU to be really pi**ed off? Feel like I’ve been conned by my own parents.
