Dude high-fives New Yorkers trying to hail taxis

If you’re an upbeat person facing a drought of high-fives in New York, then I’ve got good news. See all those people standing in the street, each raising one arm in a loose salute? They’re all waiting for something very specific: the chance to slap palms with a stranger.

Sure, some may instinctively recoil at your excited approach, fearing a run-by mugging or a punch in the face from an actually insane person—but these people make up Manhattan’s sensible majority. Others will gladly share a moment of mild amusement and mutual approval.

Now that we’ve explained that, we should really find out what those yellow cars are about.
