My son is pushing my buttons.....

AIBU!!! I know this isn't the crime of the century but my 15yr son is getting on my nerves slightly....bit off background regarding food in the house, once its bought he eats the majority of it, there is myself and his 18yr old sibling. Thats not an issue but packets of biscuits, crisps, tins juice etc which are for everyone he takes yhe whole packets to his room whilst im in bed sleeping, have told him they're for everyone not just him....latest issue.... bought 2 items for him and sibling (dessert) he ate his and siblings the following night, without asking etc. Explained it to him he would have to replace it with anything of his choice to which he just gave full attitude that the sibling didnt care so why should he replace, just because I was telling him to!!!....explained its the principal of not taking whats not yours etc and if it was the other way about he would not have been happy. Again refused to replace, to which I took a small "donation" from his room. Full attitude, mocking what I was saying and put his foot to the door so I couldn't leave, but I did with the "donation"??? Opinions!!! Its hard work teenagers with no other half to help navigate with....

That age is difficult especially in the holidays and they are always hungry. Could you get a box for his treats clearly labelled and say under no circumstances to touch anything outside that. Have plenty of bread for toast so he can't say he is starving. Or keep the treats in your room and realise them bit by bit. You could also say no moee treats as he cannot handle them properly.
I wouldn't go into his room though as that is a step too far. Does he get pocket miney..take the money out of that for his siblings treats that he eats. Does he usually find it difficult to say no to himself or is this just Summer holiday boredom?
Hopefully he will revert to normal when school comes round again.

@junebirthdaygirl started leaving tins off juice in the car and only bring in when needed. To me it was more of the defiance of not giving back what he knew wasnt his to eat. Thanks for your comments. New day.....

One thing with teenagers l found was each day is a new day. Try not to build resentment just begin afresh. I was talking to a friend who had to hide the controls in the car and take them to work ..her son is now a doctor!! Dont panic..teenagers can be a pain but they mostly come round eventually.
