After reading this tweet, I went to the completely verified wealth of all human knowledge, Wikipedia, to find out what this was all about. Here’s what I found out:
The Christmas truce was a series of widespread, unofficial ceasefires that took place along the Western Front around Christmas 1914, during World War I. Through the week leading up to Christmas, parties of German and British soldiers began to exchange seasonal greetings and songs between their trenches; on occasion, the tension was reduced to the point that individuals would walk across to talk to their opposite numbers bearing gifts.
I can’t understand something. These guys spend months trying to kill each other day and night. Then, take a week off and sing Christmas carols, exchange presents, and generally be nice to each other. And then, go right back to killing each other. Dead. As in dead. No more life. All done.
Just don’t understand.
