Please, consider the following:
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.
National High Five Day is the third Thursday of April, this year falling upon the ninteenth. I’m warning you early, so that you might be able to get some practice in, and perhaps stock up on some moisturizer.
