A bit back my mom bought hotdog buns instead of hamburger buns, so I said, "Oh mom, you're so silly." She absolutely lost her shit.

"You do NOT call your mother that, you shouldn't call anyone that!" And on and on. I thought that her reaction was manic, but I didn't want to argue.

A couple days ago at work, I pointed out an easy mistake mistake my boomer coworker did, and she said, "Oh, that's just silly... OH me, I'm calling myself silly. I would never call someone else that." Uhhh, okay?

Is silly just a grievous insult to them?
