My younger (teenage) brother is visiting me at the moment while my parents are away - he is not trustworthy to stay home alone. He arrived last night after dinner and said he was hungry - I volunteered to make him choccy cupcakes if he'll nip down to the co op with me in the car for the chocolate, as parking is a nightmare.
I wrote him a list and gave him £20 and told him he could pick himself up some sweets or something too - the list said, "Large bar of chocolate, Milk, Bananas."
We get home, I take the bag and change from him, there is 17p change and he has bought beer, crisps, sweets... and none of the items I asked him to pick up. Grr! I can't afford to just throw away twenty pounds on crap like that, especially when he didn't even ask permission.
This morning, I offer him a lift across town to school to save him getting the bus. He goes on a rant because he wants to drive my car in - he hasn't brought his car from home because, in his words, he doesn't see why he should pay for petrol when I've got a car anyway! I tell him he can have a lift or get the bus but I need the car to get to London later - besides, he drives too fast and uses his phone and ipod, and is generally a dangerous driver. Pop in the shower, come out, and he's driven off in my car leaving me with no way to get where I need to be except to pay a fortune for a taxi, and no door key to get back in the house afterwards.
AIBU to make him give me back the 20 pounds he wasted and refund the taxi I'm going to fork out for? He seems to think I am being petty but I don't think he should treat me like this.
