I never buy bog standard chocolate such as Cadburys, I can easily resist the expensive high percentage of cocoa solids stuff, not Cadburys, when my children were young I'd even break off bits of their Easter eggs if they were lying around for too long. Bad mother
although they know me so well they will on occasions buy me a box of Milk Tray, then I have no choice, other than to eat it, I am at least magnanimous enough to chuck my husband some of the less desirable ones a fudge or two. I don't buy crisps either, I love all that really bad saltiness as well.
Biscuits, I'm ok with, my husband loves chocolate digestives and can grab four or so after dinner but he is very slim so he can get away with it, happily I'm not that tempted by them, but I wouldn't buy any thickly covered all over chocolate biscuit particularly Cadburys.
Nutella is something I discovered of late, I wouldn't buy it for my own children, I think I thought it was unhealthy to have on a regular basis, but have a large jar for the grandchildren when we see them every other week, it's pretty moreish a bit like peanut butter, I could never leave that alone after I first tasted it, Not something I grew up with and like Nutella I thought I wouldn't like it. Wrong!
Other than that crusty breads, pretty much any type, I do buy some when we are entertaining or have people to stay.
Doughnuts and various pastries, I steer clear just too delicious to leave alone
