I know what you mean. I like Gayle overall and I certainly don't want to nitpick the only woman on the panel but she has certain habits. Like the pointing the finger thing, if she uses the word great she has to add "it's Tony the Tiger great", etc.
Since they've been broadcasting from home the overtalking has gotten much worse- everyone does it to some extent as it is the nature of delay but Gayle does it at another level. When a guest adds something to the greeting instead of just continuing she stops and acknowledges what they said, has to try to find where she was. Same thing happens at the close of an interview if they add an extra good bye or pleasantry. It wrecks the flow entirely.
The thing that irritates yet cracks me up is her need to interrupt by loudly saying their names. Yesterday it was "Anthony and Vlad, Anthony and Vlad, Anthony and Vlad". My favorite was the day they were doing a story on a man named Nick who got to use a lift to be raised up to his wife's window in a nursing home. Anthony and Tony were wrapping up the story and Gayle loudly interjected "Anthony, Anthony, Anthony", "Yes, Gayle", "Anthony, you have a son named Nick". The look on his face!
