It's really starting to get to me and I'm probably not dealing with it correctly. The other 2 (teen and 10) are super polite - please and thank you and just generally appreciate things.
DS8 has, from a young age, not really picked up the please and thank you without a prompt. He's definitely got better in the last year but still needs reminding probably half the time. It could be because he was 4 when I separated and his dad is rude/ungrateful often and he spends time with him without me now (he's a good dad though, but bloody entitled).
It extends though to expectation, he seems to 'want' this 'can I have that' - the others never really did this. And when we're having a drink/snack on the sofa he'll just try and hand me his cup when he's done instead of putting it on the table?! I keep reminding/prompting but then sometimes get pissed off and tell him off about lack of manners, I'm at a loss though. And I worry he comes across as really rude to others. Otherwise, he's a lovely, friendly, fun and kind boy - it's commented on by teachers etc.
I may be over reacting but it jars with me and I always notice when adults aren't polite and it bothers me. I'm sure it must be the same for many others and feel a responsibility to try and change this before it's too late.
