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.
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.
