My reaction to Renee's reaction to Carmen is that she seems to be just analyzing everything Carmen says and seeking out ways to find negativity.
The openness Rose experienced with her poetry class is one of the most intriguing aspects of this show, and the one part of the show I've enjoyed most in viewing it. Carmen feeling like she could jump in and participate in something her daughter had been part of -- and participating in the way she did -- that took some guts, and it's interesting to me that all Renee heard in Carmen's power-filled, wide-eyed amazement -- after witnessing probably an hour of poetry, creativity and open interaction -- all Renee heard was negativity.
That's ... well, it might be honest, but I think she was seeking out the worst possible way to take what Carmen was saying and focus like a laser on it, like it was the only possible way to take it.
These people all seem to be more naive than one might hope people, in general, would be.
P.S. -- Also, I'm interested in how the political statement that is made in wearing a highly conspicuous dashiki was ignored in favor of dismissing it as one more example of the Wurglers' general cluelessness.
