While you walk around the city, someone zooms past you, you look up and notice a guy on a skateboard. He winks at you before doing a kickflip, then grinding the down the rail of the stairs. He skates away and you're left there alone, you'll probably see him again soon. You walk down the stairs and continue walking, then hear another skateboard coming toward you. "Look out!" You move to your right and the same guy zooms right past you. "Sorry!" He looked a bit embarrassed.
