I was 40 last year so my dad decided he'd offer me £40k to buy a car. Admittedly, this was 8 months after my birthday (part of me thinks he forgot how old I was). It's an advance on my inheritance. Conditions were that I could only use it to spend on a car. Anything I didn't spend, would be lost.
As I don't talk to his wife (my biological mother) or his other kids (my biological siblings), I didn't know what to do, so I took the offer. He said he was going to offer them the same. In "normal" circumstances I'd have spoken to his kids to agree what road to take (accept or decline), but because I'm not speaking to them (and haven't in years because they're knob jockeys - his wife and other kids are the MAIN reason I'm single and divorced), I said yes. Why not? I didn't know how they'd react or why not?
