Of course, it is the weekend Grover Cleveland put aside to mollify Union leaders back in 1884 following the death or workers at a strike. It is also the traditional end of the season when a person can wear white (because the cool of fall is coming soon). In the US, NFL games commonly start the Thursday after Labor Day.
Of course, the guys have to make their comments about how each of them perceives this weekend. Neither character’s comments should surprise you. I did make an attempt to create a white belt for Mr. Blue.
