I had to do a training exercise at work once where I asked a colleague about her favourite thing in the world then, while she was telling me about it, suddenly lost interest and completely blanked her. She wasn’t happy to say the least, I think if she’d had a blunt object to hand I would have been on my way to A and E.
The point, we were told, was to show how your reaction to people you are dealing with can affect how they feel about you. I kind of knew that after 20 odd years in journalism, but it was still a stark reminder. She was cross with me for the rest of the day I‘d say, even though she knew it hadn’t been real.
