this most likely will not happen, if they want to add DC as a state they will probably have to make a Constitutional amendment. also when adding states the government tries to add an even number so the new state(s) don't favor one party, then why don't they also add one of the small territories (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico or the U.S. Virgin Islands), because all of those are mostly Democrats and guess what, DC is also mostly Democrats. so if the government added more states the Democrats would have an unfair advantage.
~71% percent of the world is covered in water, so if humans can find a way to make (eco-friendly) homes on top of the oceans they can greatly reduce greenhouse emissions. but there is a dark side, homes on water have a higher chance of polluting the enviroment.
just because you have a lot of money does not mean you need to use it on a big house. in fact the 1996 "The millionaire next door" (by Thomas J. Stanley) showed that most rich people live like a normal non-rich middle-class person
people keep asking "when did April fools start?", it started in France in 1582 and was called April fish day, it started because France had just switched from the Julian calendar to the Gregorian calendar. some people did not know this and still celebrated new years on April 1st, this people were called april fools (or "the fools of April") and were pranked by having a paper fish put on there back. people enjoyed the pranking so it became a Holiday!! (yay)
