The only reason Harvey calls people cunts is because he has heard HER do it! My kids have never used that word ( or not in my hearing anyway, they wouldn't dare) but likewise they never heard it at home either. TBH I still don't like or use it personally. I'm no stranger to a well chosenI brought my SN daughter up the same way I did my other children. It was harder with her, but I didn’t see why it should be any different. No swearing and manners are very important to me. ( I loathe bad manners). Also punishment was the same for them all. She is severely autistic but has understanding if you work hard at it. I now have a very polite adult daughter, who knows right from wrong. So I know she could have done the same with Harvey if she had put the effort in. They need to learn basic skills of life. She never even taught him those.
f bomb though, I'm no saint!
