The things they say - grizzling

I just asked Iris to stop grizzling as she was coming up the stairs, it's kind of understandable cos her ears are all gammy and she might have an ear ache or a headache or any number of ailments that she can't explain, but still the words "stop grizzling" popped out of my mouth.

She said quick as anything "i'm not grizzing, i'm just crying"


Which makes me wonder what is the worst grizzling or crying?
