On National High Five Day, there's no need to restrict your high fives to only the people you know. In fact, sometimes the best high fives come from random people who you've never met.
To further drive this point home, here are seven videos of people hitting the streets and getting high fives from complete strangers. Sure, some people don't reciprocate the high fives, but the ones that do leave with big smiles on their faces. And that's what National High Five Day is all about (we think). Vote for your favorites!
