Sonja has made several sly remarks this season to the group (and allegedly some to the press) about Tinsley overstaying her welcome and being a bad house guest.
"Tinsley is a very polite, correct person," Dorinda told TooFab. "I mean, if you were a guest in someone's home and you were treated like that, how would you feel? It was somewhat humiliating. Tinsley is very well raised and very polite."
Dorinda said she couldn't believe that Tinsley stayed.
"The first time that anyone spoke to me like that, I would've had my bags packed and moved into a hotel. If anyone ever thought they had to tell me what kind of guest I needed to be, it would be over with my stay and it would be over with my friendship, to tell you the truth. Tinsley is much more tolerant, and she put up with it!"
Tinsley and Sonja were friends long before the former moved back to New York City following a very public breakup with a boyfriend.
"I don't think Tinsley ever saw that side of Sonja," Dorinda said. But then again, she also said that Sonja is somewhat of an enigma.
"You don't really know her. She's not part of the group. I am, and I have been," Dorinda said. "I've lived a different life than Sonja. I was a single mom raising a daughter. She was more Ramona's nighttime friend that she'd go out with. And Ramona -- because Ramona and Luann and I were all raising children -- they were more of my daytime, you know, go to lunch, that kinda thing."
"We're actually more similar than we are different," she added. "We're in the same place. We're both not married. Our children are both raised. We don't need to have this conflict in our life."
Dorinda also dished on this year's reunion, which she said ends quite differently from the way last year's ended.
"The reunion last year we all left and we didn't even wanna talk to each other, see each other, say goodbye to each other. The great thing about the reunion this year -- we have to review a bunch of old topics and things -- but you'll see at the end that everybody leaves feeling good about it, feeling good about each other. There's a lot of solid, honest resolution."
"I felt the show this year was much more personal. People really honestly worked through stuff, and you'll see that in the reunion," she added. "We're happy to have some time off but we're happy to see each other and we've all stayed in contact. I just felt so much better. Last year, I just felt like, 'Ugh, I don't even know if I wanna come back to this whole thing.' This year, I'm excited. We all seem to be in a really good place."
