By rights, after having a night where one spends a significant portion of the allotted slumber time conversing with argumentative foremen, one should be sub-par but in fact I do believe I felt more ready for action when I woke then on a normal day. Must have been some of incandescent anger which can flare up in one from time to time if pushed.
Obviously by about eleven this had largely faded and the rest of the day slumped, then rather badly sagged and by the end it felt largely like the day might rather need to be sent for repair. No point in starting anything on a Friday before a long weekend.
I closed up shop early, allowing everyone else to get out while the going was, while not necessarily good, was at least fair.
