Why do JNs do this? I'm asking to learn, not as a rhetorical question.

I have food issues, but my JNmom has decided which ones she'll take seriously and which ones I'm making up. Gluten gives me migraines, and she enthusiastically supports my desire to stay gluten free. Yay, unsolicited support. How nice.

OTOH, eating raw tomatoes is like biting into radioactive Tabasco sandpaper cactus porcupines, and she gleefully has tried to sneak them into my food since I was a 12yo (I'm now 55!) - tucked under salad lettuce, hidden in sandwiches, etc - and when I discover them and have a fit, she mocks me and laughs like I'm a cute puppy who fell asleep in a funny position, you know the kind of "ohhhh haha look at that poor thing who can't help itself" kind of laugh?

Doesn't matter how many times I explain/yell/throw the offending food in the trash in front of her, she is convinced it's all in my head and if she can get me to unknowingly eat them, just once, that'll prove her right.

Infuriating.

I don't understand that disrespectful behavior at all.
