My DS (10) has a relatively new best friend of around 6 months, my DS is super quiet in general DS friend is the total opposite which I think is nice and initially thought it would be good to help DS come out of his shell abit. Anyway I have noticed this friend is really quite rude in the way they speak to everyone including their own parents who just seem to allow it. Parents are absolutely lovely. Friend stayed over during half term and was quite demanding, I want this I want that, snatching, didn't say please or thank you at all, I was speaking to him on the way home and he just stuck his headphone in and ignored me completely. Dropped off at home and not a mutter of a thank you. I'm worried this behaviour will rub off on my DS. I did spoke to my DS not sure if it was the right thing to do and said I felt their friend was a bit rude sometimes and he said yes mum I thought the same! However my DS really likes this friend and I wouldn't stop them seeing eachother, friends parents invite my DS over often and he's always keen to go. I'm just not sure how to navigate this behaviour when in our home
