I have recently posted about my DD2s behaviour in upsetting DD1 about her school and demeaning her potential University and course . The worst part is she is now calling me 'Thick' and an embarrassment because I don't have a degree from a top University like all her friends parents and that I have to do an OU one because I have no qualifications .
She said 'Sorry' about an earlier outburst, but she is at again calling me , DD1 and her friends.
How can I shut her up?
She has never been like this before.
