Welcome to National High Five Day
National High Five Day falls on the third Thursday of April each year, which falls this year on April 19, 2008. The holiday originated at the University of Virginia in 2002, and has since spread across the nation, and around the globe.
Imagine that while on your way to class, you pass a dignified looking middle-aged man in a suit. You, of course, are wearing the same underwear as yesterday, a pair of pants off your floor, and a T-shirt with something ironic printed on it. Instead of noticing this respectable pillar of society fifteen seconds or so before your interaction is fated to occur, and lowering your head to avoid his disapproving scowl, you take another course of action. You confidently walk forward, and at the moment of passing, you and the businessman simultaneously raise your hands and wordlessly high-five. The sound of the perfect high five resonates, causing those nearby to silently and enviously take notice. You both walk on, and likely relate the story to whomever you eat dinner with that night. There is no reason why this should not happen with alarming frequency.
