I have a new pet peeve. It’s whenever a character in a story worries about or comments on something they just ate or are about to. A couple of years ago I probably wouldn't even haven noticed it, I have diet-quotes in my head from shows I watched growing up, not because I specifically honed in on them or internalized the message, but just because for some reason or another they decided to stick. It's just so normalized, and most of us probably don't even know better to even question it at this point. I sure didn't. Now there's plenty of reasons to take issue with diet culture in stories, all of them valid, though that isn't specifically my personal trigger point. Sure, I can definitely do without disordered eating storylines, and I would honestly be thrilled if I never again saw overweight people reduced to mere caricatures in stories. Seriously, people are far more than their body size and those caricatures are just lazy writing.
Those annoyances are nothing new though. No, my new pet peeve is when it's someone with an expected healthy-ish relationship with food, especially if they have a very active lifestyle on top of it. Because it's typically nothing outrageous, usually a simple dessert; a slice of cake, or a pastry of some kind – maybe two if they're especially «daring» – and they then act as though it's going to require this massive action to «make up for it». And it breaks my immersion, because it's not even true.
