The Corduroy Appreciation Club exists and has an annual holiday? Weird.
I can't believe that they were tactless enough to choose November 11. Which in much of the world is a very solemn day, dedicated to remembering various wars. In the US it is a much smaller deal than in other countries, but we still have veterans day. Not exactly a day for celebration.
(The reason for choosing November 11 is that the treaty ending WW I specified that the shooting would stop on the 11th hour of the 11th day of the 11th month.)
Remembrance Day has become something of a misnomer, since almost no one alive actually remembers WW1. Also, there are more people alive today with a Nov. 11 birthday than died in that war. So I think it's OK to celebrate again.
Nobody may remember WW I, but there are lots of other wars that people remember. And in lots of countries, Nov 11 is the day set aside to remember it.
Personally I cannot think of Nov 11 without remembering school assemblies where a WW II vet had put together a program to impress upon us the seriousness of the occasion. In particular I can't forget a picture of a man whose throat had just been cut by a bayonet. The wall of blood coming out had not yet hit the ground.
YMMV. But for me, personally, November 11 will never be a day of celebration.
The planet Neptune completes its first full orbit since its discovery on Sept. 23, 1846.
