I'm not *sure* I disagree with the rating, but I figure if I flag it maybe someone who knows the movie better than me might be able to verify.

I do recall a scene where Sandra Bullock's character (LeAnne I believe) has lunch with her friends. Michael certainly becomes a focal point of the conversation, but it's about whether he poses some kind of risk to her daughter anyway. There is probably some chitchat about other matters before that becomes the topic.

No idea if that's enough to pass the test or if there are any other conversations that could pass the test. Thought I'd put it out there.

This rating is incorrect.
Besides the 3 'ladies do lunch' scenes there was a mother, daughter conversation and cheering section at the daughter's volleyball game.
Sandra Bullock also had a full scene with Michael Oher's mother that was as much focused on the mother as it was Michael.

There is a scene where Sandra Bullock reads to her daughter, and when she speaks to the tutor played by Kathy Bates. While she is interviewing the tutor Michael, she asks her questions about her work experience.

Leanne speaks to Miss Sue about her work experience and Miss Sue being a Democrat but not specifically about Michael
