Did you know that one thing unites most of the world in peace and celebration? No, not our essential humanity or our shared home that we like to call Earth–it's actually Independence from the British Empire!

(Turns out the above is not true, since lots of these holidays cluster; I guess when one wants out, the neighbors want to go along for the ride!)
