A female pedestrian was hailing a cab but in the perfect hand position to give her a high five, so I did! I couldn't resist! My good friend riding behind me almost fell off his bike from laughter and he said that everybody around the lady started cracking up as well. She looked at her hand with total confusion, haha! True story.
