Carrie did talk about how hurt she was that Charlotte didn't offer to loan the money, but then, IMO, she passive aggressively "hinted" that Charlotte should be the one to offer her money because, as quoted, she doesn't even have to work! She didn't actually demand that the money should come from selling the ring, but IMO there sure is some subtext in "what is that on your finger?" I guess if Charlotte said back "And what is that on your feet?" she would have been out of line. AND, when Charlotte said she's volunteering because she can't find a job (even though she was under no obligation to explain herself), I would have felt like a Grade A ass.
I do have to say, I am NO Charlotte fan in the late seasons. What happened that she became such a shrieky whiner? I want to smack her into next week when she ranted about how offensive "Tea for Two" is at her tap class.
Regarding Carrie screaming, I think she has two especially annoying screams (yes, even worse than when she saw the squirrel). When they were talking about hot actors and she screamed when they said at the same time "Russell Crowe." That was in a restaurant, I think others eating there who were subjected to that should have been offered a free meal. The other, which IMO is the worst, was in the one where they went to a fleet week party...first she screams when her skirt blows in the wind, and then when she gets rained on. It's not even that she screamed (I probably would too if the wind blew my skirt like that or if the rain would ruin my blowout), it's how she screamed, it sounded like Alvin and the Chipmunks got injured.
