17 year old and is currently trying to find a part time job to fit round college. I have saved a few thousand pounds towards a car or travel etc for him. He's been taking it out in dribs and drabs increasingly regularly and has nothing to show for it. I've found out he's smoking weed. He is aggressive and demanding Igive it to him when he asks as it his " his" money, and I havent restricted his siblings access to theirs ( who have used it for legit things). Why on earth should I facilitate his habit? Or should I just let him squander it and hope he learns a lesson when there's none left.
