DS (13) and his best friend at school play Fortnite. His friend's parents do not allow him to buy anything Fortnite related (Battle passes and what have you). I leave DS to buy whatever he wants with his birthday/xmas/pocket money.
So DS asks me if his friend can give me £20 and can I pay for some Fortnite thing. He caught me when I was really tired and I agreed without asking questions. Later I find out the reason behind it and obviously not pleased because it makes me complicit.
DS is begging me to do this favour for his friend. He says he could have lied and made up a story in order to get me to buy this Fortnite thing but we have a good relationship and according to him he has never lied to me.
I don't know the parents, I've said hello once or twice. AIBU to just do this one-off thing?
I'm not sure it's relevant but the friend is a super high achieving gifted/talented student who never gets into trouble and money is also not an issue - they're a very rich family. I really don't see the harm myself but obviously not my call.
