There you are in a meeting when someone pipes up with a problem they’ve spotted that needs fixing and your jaw drops open because you know perfectly well that they were the person who caused the problem in the first place.
What seems really odd is that they’ve just lobbed the problem into the conversation with no intention of fixing it themselves but equally not trying to offload it onto anyone in particular. To make it worse they seem to be over-emphasising the seriousness of the problem. Guilty conscience perhaps?
