she's never hit me as mentally handicapped
I have seen two or three interviews with her, and I share your impression. Naive, yes, but not dim-witted. To hear her apologizing for using "bad language" was funny, but she also made good observations about how in her home town it would have been unthinkable for her to date a black guy (at that time she had filmed several scenes with black partners). She also didn't hide that she disliked the way some directors and male performers in the industry treat female talent (basically the same thing that at about that time Yhivi gave as one of her reasons for stopping doing porn).
