I was at an executive briefing with some major customer at the briefing center. We were a couple of days away from from some new product launch that was relevant to the briefing but were under orders not to say anything. Anyway, my--I think--manager's manager decided to sketch a few TBA things out on the whiteboard or blackboard anyway when Edson walked in to say hello. She very unobstrusively managed to erase what was on the board before Edson noticed.
