@Loop_Stratos the friday after thanksgiving.
More or less the start of the xmas shopping season. In the usa (and some other countries, but in some its more an e-commerce thingy) its a very popular shopping day.
Shops often attract customers with special promotional sales/gifts then, and they open very early... as a side effect sometimes violence occured between shoppers...
Did you consider that this is no good to people who live where thanksgiving isn't a thing? The only interesting thing that happened yesterday was that it was Cake Wednesday in maths class. (My maths class has cake every other Wednesday. )
