Some friends came over today with their children and their 10 year old dd told ds1 (9) and ds2 (7) a rhyme that included the works s..t and f...ing b..ch. I'm astonished at her really as her parents are extremely hot on manners, rudeness, how essential it is to be nice, even the word 'stupid' is banned in their house. If they knew what she had said they would be absolutely horrified. I am very good friends with the mum so should I tell her?
