The writers note this is not ordinary and then go on to blame it on "the spotlight." Really? What I hear is that Michelle's a terror to work for. That she's prone to screaming fits. That if you cross one of her friends in some intended or unintended manner (especially Valerie Jarrett), you're griped out and called to the carpet. And when this happens, as it did recently, over something as minor as grabbing the wrong Starbucks coffee, I think the term for Michelle is "horror." Though you can choose something stronger if you prefer.
She has turned on devoted and caring women who only wanted to help her. That's in large part due to the fact that she has no idea how to interact with people working for her -- it's a fairly new development. She's also gotten very stuck up in the months in the White House and that feeds into the problem.
