From the distance of 36 hours, Prudence can see that yesterday's meeting between the union delegates and the big cheese was really laughable. At the time it was infuriating.
So, aside from the fact that the big cheese just lied - or at least he said a lot of the right things, and Prudence just plain didn't believe him - there was one perfect moment.
Right near the end of the meeting, a cockroach, whose father must have been a shetland pony, wandered along the floor past Prudence's chair.
A perfect metaphor.
