I'm not surprised by her missing the closure call. She's been an absent CEO for the majority of her 3-year term. She makes time to meet high level politicians, TV personalities, etc. - but misses many town hall calls.
She is like cotton-candy. When you first meet her - you like her! Sweet - but very soon you realize there is no substance to her. She has one finely crafted message she uses in multiple public situations, but once you've heard it...multiple times...you realize the cotton candy is gone...
