I've noticed that both my dds 5 and 7 seem to be insecure round their peers, and will often be very rude to/about me or to/about each other in their friends' company. I REALLY hate this and find it idiotic as I think it shows a lack of respect for their family and for themselves. I would expect them to have the integrity to defend their family if anyone else denigrated it, rather than joining in. How do I get this across without being too heavy handed?( which is how I feel).
