One of my 6 cats, Pee Pee (don’t ask) has the most obnoxious meow of any cat I’ve ever known (and I’ve known many). It’s a grating, loud, low-pitched, monotone meow of 5 seconds duration. Whenever she see’s me, she assaults me with a long string of her grating, ear-splitting meoooooooooooooooooooooooows.
Note: Pee Pee is the lone female in my clowder of cats. I suggest no correlation between female cats and female humans, however (I’m not stupid, and don’t want my genitals kicked).
Pee Pee meows whenever she is hungry and she is always hungry, even 5 minutes after eating a big bowl of Kit & Kaboodle. IOW, she meows all the time.
So, the last time Pee Pee meowed (20 seconds ago), I looked her in the eye and said, I don’t like your tone of voice, young lady! She looked me back in the eye with disdain and replied with a 10 second meow that was louder and more obnoxious than ever.
It can be incredibly insulting. Just like saying “wow, you certainly do like cake!” can be both taken and meant as an insult depending on the circumstances. Say it to me today and I might just smile and say “Yep, I sure do!” and go on enjoying my cake. Say it to me ten years ago as I was 30 pounds heavier, and I might not take it so “lightly” if you catch my drift (and doubly so if I happen to not be eating any cake at the time).
But to the subject at bar, for an example of how criticizing someone’s tone can go beyond even mere insult to incredibly hostile see tone policing (and, again, if someone can’t imagine how you could reasonably take issue with their tone, that may greatly increase the risk of them taking it as an insult, not jumping to “Oh, haha!” like it’s a joke).
If someone did that to me out of the blue, I’d be confused, hurt (I don’t like “jokes” like this) and then angry. I’d think twice about speaking to you again for a while, unless absolutely necessary.
Granted, a lot has to do with your own tone of voice and delivery, but if it was said in a sincere, chastising way for no good reason, I’d not be amused. At all.
