I'm surprised by this reaction. Here's a more sympathetic reading: Sheryl thought Kim showed great potential and was doing great work. HOWEVER, it was clear to Sheryl that the presentation was super awkward from an audience POV. The problem would probably never be obvious to the speaker, because we usually are unaware of our Ums while giving a presentation. So Sheryl only wants to help the speaker. Is it a little embarrassing? Maybe, but it shouldn't be. Now the author is a better speaker, and better professionally for it. Isn't that a great outcome?
