The disrespect is out of control
I have a great relationship with SKs - they don't talk back to me, they listen the first (or at least second) time if I ask them to clear the table, clean up common areas, etc. They know I don't respond to whining, they have to 'use their words' /please thank you, etc. But I have not made myself a disciplinarian or set rules that DH didn't make first.
However, SS10 is extremely disrespectful to his father. It is painful. He will ask him to make his bed, and the whining, the sarcastic talking back, the "why, that's so stupid - I'm too young to clean" (thanks BM)
When I hear it, I talk to DH in private about how inappropriate it is to speak like that to the man who puts a roof over his head! SS wouldn't have a bed to sleep in if it wasn't for him! The ungrateful, entitled attitude is too much. It's never directed at me though and if he was my own son, I'd insert myself and tell him he absolutely doesn't talk to his father that way... but the fine line of SS vs BS makes that more difficult.
Do I just pick my battles and leave this one alone? I told DH it's annoying as hell with a 10 year old but the source of an ungrateful bratty attitude is only going to magnify as a teenager if it's not addressed harshly now. Or are my standards too high?
