Dont overlook that some actors (on the CT level) possess an "exhibitionist" gene.

We had a similar situation in a recent show where an actress in her 30s couldnt remember that it was inappropriate to change in front of the 11 year old boy who was also in the cast (I'm talking bare breasts). She had to be taken aside and "talked to" by the producer. She also apologized (profusely) when the situation cooled down, but everyone was convinced it was a personality disorder.

All I could think was, "Man, where was she when I was 11?"
