(The first was locked some time ago, and I couldn't find a second one. So, here it is!)
Basically, post an interesting tidbit about your nation's culture (but this can include military, legislative, or any other interesting facts) that you think the nation above would find a bit shocking. (I would recommend skimming through factbooks or looking for previous posts on this thread for the best possible shock!)
I also ask you do not post so frequently. I recommend waiting until two or three other nations have posted before you do so again. Posting about, say, a half-hour after the last post is fine.
Example:
Nation 1: "Our people hate homosexuals, and stone them to death!"
Nation 2: "We are a country full of lesbians."
Nation 3: "We have perfected wormhole technology."
Nation 4: "A Social Democrat won our last election for president."
Nation 5: "A popular pastime in our nation is paying strippers to kick us in the gut and tell us we don't matter."
And so on...
Since I have nothing to shock, I get to wait.
