I think Dorinda needs to watch the prior seasons before she casts judgment on Heather and Bethenny. Both have had to deal with Sonja and her products, drinking etc.
And that goes for dealing with Ramona and Luann as well. Dorinda is liked by them and so they are nice to her. Ramona from the start has been vicous and rude to Heather and so obviously Heather has a different take on Ramona. JMO.
And Bethenny has a history with both and it has not always been pleasant.
