I got the snarky little sister vibe. Her attitude was why should I have to suffer/eat in hiding just because you can't control yourself? This is a valid feeling that many people who don't have food issues have. My boys could never understand why I can't have a bag of chips in the house and not eat the whole thing. Now I tell them if they want that stuff they need to eat it out of the house or I will buy it for special occasions only when I know it will be eaten and gone. I am home all day so I hear any of that stuff calling to me.
My other problem is that I am a really good cook so even if I don't buy it I just make it. Yesterday I wanted macarons so I made a batch. Next step will be to stop buying ingredients, too.
