I used to feel sensitive, very, then I realized that the small angelic person I made had the other side that worked just as powerfully and knew without a shadow of a doubt that bad manners or rude behavior was the same as brat to others and I gave up the worry that she would always hate me or remember one instance of me being angry and telling her what her behavior had created in others.
Now I make it clear, when she throws fits or yells or has attitude I call it what it is, attention seeking selfish power hungry behavior that will not get a reward. I won't give her more time, more love, more attention, or figure out why she's sad, shes advanced intellectually and I treat the behavior as it is. I make sure she knows it is not acceptable as a kid or an adult. When she's out now she notices that kids get goodies for screaming and she loses all kinds of extras (t..v. games, movies, library, swimming, etc.,) for related behavior. I've told her she is entitled to her feelings and always to talk about them, just be aware some reactions won't be the ones she's seeking, that if she wants my behavior to be more favorable then she has to act in a way to gain that behavior.
She knows the princess in the movie has good manners and the evil step sisters are angry mean and less the lovely.
I suspect your DH simply called it like it was, I'd like honest reaction to...pretend or false reactions. If you want more diplomacy then ask for it, remind him when your son is behaving X that you would like a cushion for your own sensitive nature. Not unfair or wrong, just is what it is. My DD is a wild, amazing, loud, difficult natured person. I do not love her less for the honest matter that she's like five kids at once! she tests every limit every time every minute, much more energetic then I was as a kid.
My DD isn't always a brat, she isn't always an angel, but sometimes she can be one or the other for a while.
